100 Miler

Minimum Pace Time: 30 hours

On this course you will experience two of the most photographed land features in the country- Antelope Canyon and Horseshoe Bend of the Colorado River. After traversing the desert sand and slickrock to reach these unbelievable features, the run finishes out with 6 laps on smooth single track around the plateau that the city of Page, AZ is built upon, with jaw-dropping views of Lake Powell. 

Runners start with a 5 mile desert traverse on a sandy doubletrack with a little slickrock and a slot canyon mixed in.

Near mile 4, runners will drop into the first slot canyon of the day, at the bottom of which is Antelope Aid Station.

After the aid station you'll enter a large, very sandy open wash, which you will follow south for about 3 miles to the entrance to the incomparable Upper Antelope Canyon. (This is one of the most photographed slot canyons in the world.)

Navajo guides may be posted along the route, as travel on tribal lands typically requires their presence in order to visit the sacred sites. After passing through the slot canyon, runners will climb over a sand dune and pass through another small slot canyon on the return (since the canyon isn’t wide enough for two way traffic.) You’ll return to the Antelope Aid station for the second time, then retrace your footsteps back towards the starting line for about 3.5 miles, where you’ll split off from the way you came and head west toward the Horseshoe Bend/Waterholes Canyon leg. Slickrock Aid will be about a mile into the desert after crossing S. Coppermine Rd. The trail to Slickrock Aid is very soft sand.

From there, runners will traverse another open desert for about 3 miles before reaching the famous Horseshoe Bend of the Colorado River. An aid station will be set up near the parking lot of this spectacular overlook (Horseshoe Bend Aid).

The next section weaves through slickrock along the rim of the Colorado River, in an area that few humans have traveled which offers views that are beyond words. This section can be very challenging to keep a steady pace due to the constant elevation changes, slickrock, and sand that you will be running through. It does however offer some amazing vantage points of the Colorado River. You might struggle to want to put your camera away.

After crossing back over Hwy 89, runners will fuel up at the Waterholes Aid station before dropping into another gorgeous slot canyon. The aid station is located near the bridge).

After about a mile in the slot, runners will exit and head back towards the city of Page on a long, exposed, and sandy desert traverse which takes you through the Horseshoe Bend and Slickrock aid stations for a second time.

Upon entering Page and climbing up onto the plateau which the city is built upon, the route ties into the smooth singletrack of the Page Rim Trail that you will run 6 times, "washing machine style"(i.e., clockwise, counterclockwise, repeat). The latter 50 miles are locked in on the smooth ten-mile loops of the Page Rim Trail where you'll have aid stations every 5 miles that you'll make repeat visits to. This is a fast and very runnable ten mile loop with 4 road crossings and spectacular views of Lake Powell and Glen Canyon Dam.

The accessibility of this loop trail makes it logistically perfect to plan and prepare for the long night ahead with your drop bags, and for your crew and pacers to support you. And since the Page Rim trail circumnavigates the city of Page, your crew will never be more than a few minutes away from their hotel room or campsite, so you won't have to worry about their comfort.

Avenza Offline Course Maps

Ultra Marathon Aid Stations

  • Water
  • GoGnarly electrolyte drink
  • Fresh-cut fruit
  • Soda
  • A variety of both salty and sweet items

After mile 26, the aid stations will also have real food that may include:

  • Boiled potatoes
  • Tortillas w/ Nutella
  • PB&J
  • Turkey sandwiches
  • Dill pickles
  • Chips
  • Candies

All aid stations are stocked with self serve aid stations supplies such as anti-chafing agent, and sunscreen. In addition, we will have a limited supply of gels, salt caps, and electrolyte caps. 

At our busiest aid stations we try and staff a medical volunteer to help with larger issues. See your race guide for more details. 

All aid stations have composting toilets.

Race Weekend Schedule

*All Distances Start and Finish at the Page Shores Amphitheater staging area.

Pre/Post Race Meal

For the race meal, you'll have the choice of a Navajo Taco or wood fired pizza. You must present your bib stub to redeem your meal, which will be available at check-in on Friday or from 2-10pm on Saturday. Crew and spectators can purchase food at the finish line.  

Time Requirements

All who cross the finish line will receive a finisher award regardless of finish time. However, if you finish past the minimum pace time, you will be disqualified from the race and receive a DNF.

During the race, any runner may drop down to a short distance to receive the shorter distance’s finisher award. Doing so will disqualify the runner from the original distance and will be listed as a DNF at the original distance.

We publish a minimum pace time as a reference for the minimum pace you must maintain to finish before receiving a DNF. The Race Officials have the right to remove anyone from the race for any reason.

“Grim Reaper” check points are certain times cutoffs in the race that you must pass before the posted time or you will be required to drop out of the race. Non-Compliance with the Race Officials instructions will result in a DNF and may result in a ban from future events at our discretion. There are 4 Grim Reapers times for the 100 mile distance, and 2 Grim Reapers times for the 50 mile distance. 

Overall awards will be scored based on gun time.  Both gun time and chip times will be published.

Aid Station Info

At each Aid Station there will be a designated area for Drop Bags that runners wish to have returned to the finish line for retrieval. Drop bags will be returned to the starting line throughout the day, but it is the responsibility of the runner to put their drop bag in the “return” area.

Here is a tentative list of items that you can expect to be found at all aid stations: water, an electrolyte drink, a variety of fresh cut fruit, several salty items and several sweet items, soda, and first aid supplies.

Aid stations after mile 26 in the race will also have real food that may include boiled potatoes, tortillas w/ Nutella, PB&J, turkey sandwiches, dill pickles, chips, a variety of candies, anti chafing agent, sunscreen.  

We will have a limited supply of gels, salt caps, and electrolyte caps. Remember this list is subject to change. If any item is of critical importance to your ability to finish, please consider putting it in your drop bag. While we want to do our best to help each runner finish the race, food selection is often a guess as to what each runner will want or need, and we occasionally guess wrong. For example, if you always need a Coca Cola soda at mile 80, do not count on the aid station to provide this; you should put it in your drop bag.

The 100 miler will pass through 20 fully stocked aid stations.
The 50 miler has 10 aid stations.
The 55K has 8 aid stations.
The Trail Half Marathon has 3 aid stations.

Drop Bags

Personal Drop Bags will be allowed at the following 4 aid stations

  • Horseshoe
  • Water Holes
  • Page Rim
  • Powell

Please follow these guidelines: 

  • All bags must be labeled with name, bib # (in large print), aid station, and race distance.  Optional, but a good idea if your label comes off, is a card inside with the same information and contact information.  Please label your bags the day before the race on your own or at check in.  Trying to label your bags on race morning is not a good idea.  It is often dark and busy. 
  • All drop bags must be left in designated drop off location by 8PM the night before race day.
  • No valuables or fragile items in your drop bags. We are not responsible for any lost/stolen items.
  • Watch the weather forecast.  If there is any chance of rain, place your items in zip lock bags inside of your drop bag.
  • Minimum size:  Gallon size freezer zip lock.  No grocery store plastic bags or garbage bags..
  • Maximum size:  Shoe box for single pass and daytime aid stations.  Small duffle or small carry on for multiple pass aid stations.

Note: Alcoholic drinks are prohibited at this race and are not allowed on the Navajo Reservation. Breaking this rule jeopardizes our permits and will result in immediate disqualification and may result in a ban from future events. Alcohol within Page City limits is allowed, but please refrain from posting your consumption online.

Pacers & Crew

Crew access is allowed at the Horseshoe Bend, Page Rim, and Lake Powell aid stations. However, due to limited parking and high runner numbers, crew must be shuttled in to the Horseshoe Bend aid station from the start/finish area. Shuttles will pick up/drop off crew approximately every 15 minutes while the aid station is open.

Crew should park along 20th street and walk up the trail from the start/finish parking area to the Page Rim aid station or crew their runner from the parking lot. Click here for directions to Lake Powell Aid Station

Pacers can be picked up for the 50 mile and 55K races when the runners pass near the start/finish area on their way to the Page Rim Aid Station.

Note: You are responsible for the actions of your crew and pacers. If their behavior is deemed inappropriate by race staff, you will be disqualified. Please let them know this and only choose crew members that will treat our volunteers and staff with respect while you are out on the course.

Due to the remote location of this race, we will not be able to provide live updates for your friends/family to follow you from home. We do have satellite phones and/or radios at the aid stations so that we can account for runners on the course and keep communication lines open among our staff members, but we do not have the ability to communicate runner whereabouts to your loved ones during the event.

If you would like to let friends and family know your status on the course, you can text them from the areas of the course with cell service (there are many points on the course where reception is good enough to get a text out, but it can be difficult to get a phone call out.)

If you're worried about your cell phone battery, you can turn it off after sending a text, leave it in airplane mode, or carry a small battery backup device. There are also apps available such as Endomondo which will automatically update your whereabouts when you come into a reception area. (These apps tend to drain your cell phone battery and the use of a battery backup device will be necessary if you plan on leaving it on for the duration of the event.) 

Race Rules & Guidelines

The main route will be marked with pink flags.  Any route variations unique to your distance will be marked with the color of your bib. Any tricky junctions will be marked well with signs and flour arrows. A piece of highly reflective tape is attached to each trail marker that may be encountered at night. 

It is the responsibility of the runner to check in at each aid station (coming in only, no need to check out of the aid station.) Seek out the aid station worker wearing the fluorescent orange vest and give them your bib number. Failure to check in at an aid station can result in disqualification. If you drop out of the race YOU MUST TURN IN YOUR BIB TO THE NEAREST AID STATION CAPTAIN. If you fail to do this, you will be responsible for all search party costs.

Finish Line

We hope that you will join us at the finish line for as long as you’d like to welcome home the other finishers. One of our goals is to create a welcoming environment for you to hang out with old and new friends. We will have the following amenities present at the finish line to keep you comfortable- seating, fire pits, Navajo tacos, pizza, heated tents, drink recovery tent, medical tent, and a camping area.

Awards & Swag

A variety of unique, hand made finisher awards will be available, including Navajo jewelry pieces, ceramic mugs, and various crafts handmade in the Copper Canyon of Mexico.  Each of our awards is unique - you can choose the one that speaks to you. Special awards will be given to the top 3 overall male and female finishers for each distance as well. A Navajo family will also be selling some of their hand made jewelry at the start/finish line. 

Zero Waste Event


All Vacation Races events are zero waste, with the goal of sending no trash produced at the event to the landfill. We've created a system that recycles/reuses everything, but it requires your help to make it work. Please place trash in the appropriate containers. Littering on the course will result in disqualification.


We also use Great Outdoors Composting Portable Toilets which conserve water, eliminates the use of harmful chemicals, and create a nutrient rich soil amenity. It is the best pooping experience you will ever have. To learn more or to have them at your event visit or ask the race officials for more information.


We encourage all runners to carry their own form of hydration. Whether it be a cup, handheld, waist pack, or running pack- it’s up to each runner’s preference. We do not provide disposable cups at aid stations or anywhere at the event.

However, we will have reusable mugs at aid stations that are washed after use. There will be water and recovery drink at the finish line, but no cups. Please use your own methods to fill up at the finish line. We will have some limited compostable cups, but these are unnecessary if your bring your own cups.

Rocky mountain and Joshua Tree were the two hardest races I've done, but they were completely worth it! Grand Canyon has so far been my favorite! Beautiful course, spirited people, and amazing staff. Not to mention the race shirts always have great designs! My goal is to complete all NP half marathons. I will be doing Zion, Yosemite, and hopefully Lake Powell next year 2018! Thank you Vaction Races for the fun times and everlasting memories.

Travel and Lodging

Getting Here

Las Vegas International Airport is about 4 hrs from Page. A quick scenic detour would be to drive through Zion National Park on Hwy 9 to Hwy 89, then south to Kanab and east to Page.  (This would add about an hour of driving time.)  

It is about 4 1/2 hours from Phoenix to Page, but the south rim of the Grand Canyon is next to this route, making it easy to plan a side trip.  

Salt Lake City is 5 hrs and 45 min, but this route passes within 15 minutes of the entrances into both Bryce Canyon and Zion national parks, making it convenient to detour and see these places.

Lodging / Camping

Click here to view a list of hotels located in the small city of Page, AZEach of these hotels offers quick access for your crew to meet you while you’re running the Page Rim trail, which encircles the mesa that the city is built upon. 

Lake Powell Resort is a luxury resort located on Lake Powell, a ten minute drive from the starting line. They are offering a discount to those participating in the Antelope Canyon Ultras. The rate is $69 + tax and fees for the lake view, marina view or traditional guest rooms. Book early and get the lake view. Use the promo code: ULTRA at or by calling central reservation at 888-896-3829. Valid March 7-11.

We will have portable composting toilets set up from Thursday through Sunday at the slickrock amphitheater staging area for runner use. 

Things to See and Do

We realize that the races in this series are out of the way for most runners, and it may be the only time that you visit these breathtaking areas. One of our biggest desires at Ultra Adventures is that you walk away from this event having fully experienced what the region has to offer. Even a 100 mile course can only capture a portion of these unique areas. We want you to get into and explore the heart of the national park, walk through that remote slot canyon, see that incredible overlook that is not part of the course. Most often, these spectacular areas are protected as part of a national park, monument, or wilderness area where races are not permitted as part of the management plan. These are often the areas most frequented by tourists, but  are nevertheless places that we feel you must see while you’re visiting. It is our hope that through a more in depth exploration of the area, you will become more connected to the local landscape, thus creating more stakeholders in its preservation.

Here is our list of favorite trails in the surrounding area:

Buckskin Gulch: (distance varies, minimum- 3.5 miles out and back from Wire Pass trailhead to petroglyphs and Buckskin confluence)- Take picture anywhere in Buckskin Gulch- can be accessed from Buckskin Gulch trailhead or Wire Pass trailhead.  Click here for trail description.   If the conditions are right, you can make it all the way to the Paria Confluence.  If there is a lot of standing water, turn back. Attempting to run a through route this time of year is NOT RECOMMENDED.  Click on this story to read why.  You will need to pay the$6/day hiking fee to the BLM for this leg (envelopes available at the trailhead).

Cable Trail to Colorado River- Take picture at the Colorado River.  This one is easily accessible from Page, located just across the bridge on the opposite side of the canyon.  Click here for trail description.   Click here for a video clip

- Cathedral Wash, Jackass Canyon, or Soap Creek to the Colorado River-  Choose just one or all three of these canyons to access the Colorado River within the boundaries of Grand Canyon national park. If Hwy 89 is still washed out and not operational at the time of the 2014 event, you may want to do one of the alternate Trifecta options listed below as the current alternate route adds an extra 45 minutes driving time. Take a picture at the river.  Click here for trail descriptions

Paria River- Your feet will get wet on this one, but you really should check it out if you have the time. February is not the ideal time of year to go deep into the Paria due to the cold and ice, but it is amazing nonetheless. 

Wahweap Hoodoos/Toadstools- These hoodoos are pretty unique.  Big boulders balanced on tall, narrow bases.  

Navajo National Monument- While the guided hikes into the canyon to see the ruins up close are not offered in the winter months, you can still get an amazing view from the opposite side of the canyon via a trail from the visitor's center that's about a half mile.  This would be a nice and easy post-race hike to do, and I highly recommend driving through Shonto if you're coming from Page.  

Lower Antelope Canyon - Must be accompanied by a Navajo guide.  Price is between $25-$30, depending on the company.

Kayaking Lower Antelope Canyon (kayaks can be rented in Page and fastened to almost any vehicle).

Kayaking the Colorado River above Lees Ferry - Unbelievable!!  Your only chance to paddle the Grand Canyon is between Lee’s Ferry and Glen Canyon Dam, where it’s not officially part of the national park.  Due to limited permits issued to rafting companies, the waiting list and price make rafting the Grand Canyon out of reach for most. Click on the link for info on kayak rental and a ferry/tow upriver service.

Rainbow Bridge National Monument (via boat or trail)- While this one is pricey ($125) due to the 3 hour scenic boat ride (each way) to access it, the arch (natural bridge) is unlike any other you’ll ever lay eyes on.  Boat trips are limited to Saturdays in the off season unless we get 20 runners to sign up for a Friday trip. Contact Lake Powell Resorts if interested. 

Navajo Mountain to Rainbow Bridge- (35 miles round trip)- This can take the place of 3 trifectas as it will require a lot of planning and is truly epic, traversing sacred lands to the largest natural bridge in the world. I will be very jealous if you're able to get this adventure in during your trip as it has been high on my bucket list for many years. Make sure you get appropriate permits and have maps and supplies for the worst case scenario. It would be best to hire a Navajo guide for this one. 

The Wave (Coyote Buttes)- I wish it were possible to include this at the top of our list. Such an amazing hike and it's so close (shares the same trailhead as the Buckskin Gulch/Wire Pass hike).  But the BLM only gives out ten permits a day and has up to 90 applicants, so there is a daily lottery, for which you must drive to Kanab and be present just to be in the lottery. Call the BLM office found in the above link for more info.

White Pocket- This is almost as cool as the Wave (from what I hear)- Only problem is that it's a long 4wd approach so it's very difficult to reach.

  • Mike B says:

    How is the 50m for using minimalist shoes? Usually anything besides driveway gravel is fine for me.

    • Kaelee Clifford says:

      Hi Mike – This course all about the sand. If you’re find in sand you should be okay.

  • Dot M says:

    Looking to do the half in antelope canyon. I am normally a road runner and am worried how much single track there is on the half distance. I ran this route years ago and most seemed like it was on a dirt road or dirt path. Are there any really hard sections for a newbie off roader on the half course?

    • Kaelee Clifford says:

      Hi Dot – You shouldn’t have any trouble on this course. There is a lot of single track but it is totally runnable for a new trail runner.

  • Maricarmen Rodriguez says:

    Is this event for expert runners and hikers? I love nature. I just started running about 2 years ago. I am thinking about taking the next step – that is moving from 5k and 10k to half marathon and this event will be an amazing way to do that. Thank you in advance.

    • Kaelee Clifford says:

      Hi Maricarmen – This course isn’t necessarily for experienced runners, but you will want to be trained and prepared. There is a 5 hour time limit for the half marathon course, so as long as you can finish in that time you will be fine.

  • Tabatha Collins says:

    Hi! I’m curious if any of your ultra running races are certified or sanctioned by USATF, IAU, or IAFF? I’m trying to set a world record in 2019 and this is one of the requirements. I’m specifically hoping to race Antelope Canyon 55k or 50 miler.
    Thank you!
    Tabatha Collins

    • Kaelee Clifford says:

      Hi Tabatha – The races are not certified with the USATF, IAU, or IAFF.

  • Anita says:

    Will there be porta pots on the 50 milie course/near the aid stations or just at the start and finish?

    • Kaelee Clifford says:

      Hi Anita – There will be porta potties at all the aid stations on the course.

  • Richard Burger says:

    the 1/2 marathon trail is it as good as the longer ones or are they the best.? the pictures and video look great would be disappointed if I came all that way and that was not what I was running.

    • Kaelee Clifford says:

      Hi Richard – The half marathon trail is beautiful, but half marathoners will not run through any slot canyons. The 50 mile and 100 mile races go through the Antelope Canyon, while the 50k runs through Waterholes Canyon.

  • Angelet says:

    For the 50 Miler is the course all sand? Runners must pass “Grim Reaper” Check… what’s this?

    • Kaelee Clifford says:

      Hi Angelet – The course is very sandy. We highly recommend gaitors for this course. The Grim Reaper time is the hard cutoff time you must hit to avoid being removed from the course.

      • Angelet says:

        Thank you, Kaelee. One more question: How does a person on the East Coast train for this race with the difference in elevation and terrain? Would love to consider this race, but Im worried about the altitude difference and all.

        • Kaelee Clifford says:

          Hi Angelet – I would find somewhere sandy, maybe the beach, to do some sand running. And then find some hills to add into your training.

  • Jen says:

    For 2019, at what miles/times are the grim reaper checkpoints on the 50 miler? It determines whether I sign up for 50 miler or 55k.


    • Kaelee Clifford says:

      Hi Jen – They will be similar to this year’s times but I don’t have the specific times yet. I’ll post here as soon as I find out.

  • Jesse says:

    Hello, 2 things. Do you have the grim reaper times for the 100m, also do you have a better image of the map that could be emailed to me? I tried printing the one off the site and cant really make it out. Thanks!

    • Kaelee Clifford says:

      Hi Jesse – The grim reaper times haven’t been posted yet but they will be very similar to last year’s times. I am checking to see if there is a better map for printing.

  • Katie says:

    I ordered two shirts as add-ons when I paid for my half marathon when will I receive those?

    • Kaelee Clifford says:

      Hi Katie – The training shirts are mailed after the first price jump, so after July 23rd.

  • Jenna says:

    I see the 50 miler is sold out. Is there a waitlist and how do we get on it? For now, we’ll probably rego for the 55K but would prefer the 50 mile.


  • Jessica Weisner says:

    Are you allowed to wear headphones for music on the course?

    • Kaelee Clifford says:

      Hi Jessica – Yes, you can wear headphones on the course, just be sure to be aware of the runners around you.

  • Bernard Hohman says:

    I am planning on running the Antelope Canyon 100. I see that there are two “grim reaper” cut-offs for the race. Can you tell me what aid station and what time these hard cut-offs are?

    • Kaelee Clifford says:

      Hi Bernard – I apologize for the delayed response. The grim reaper times and locations have been confirmed yet but they will most likely be very similar to this year’s race: They are Antelope Canyon (first pass) before 7:30 am and Horseshoe Aid Station (first pass) by 12:30 pm on Saturday. These times can vary – we will post the as soon as possible.

  • K says:

    how far is the lake powell resort from the start line?

  • Bill Angotta says:

    Hello. We ran the Yosemite half in May of 2018 and are considering this half for our 2019 destination race.The scenery looks incredible. Are the pictures on the site from the ultra runs or will we see the same on the half marathon?

  • Becky says:

    Is the 50 or 100 mile race an ITRA point qualifying event? Thanks.

    • Kaelee Clifford says:

      Hi Becky – Yes, they will are both ITRA qualifying events.

  • Janel Stewart says:

    Can you tell me more about the charity bibs? Which charity receives the money? What if we do not raise the minimum? Do I collect money?

    I can’t seem to find info on the site ? Is there a link?

    Thank you!

  • Anna says:

    Dear all,
    Is there a waiting list for the 55 k? I saw that registration is closed already?

    • Kaelee Clifford says:

      Hi Anna – Unfortunately, there is not a waitlist for this event. There are some charity bibs available – check out our charity bib program here:
      You can also try to buy a bib from another runner who cannot make it. We usually see runners post their bibs for sale once refunds are no longer available – December 17th. The best place to find bibs for sale is on our Facebook page, Ultra Adventures. The last option is to sign up for the 100-miler and only run 55k. Doing it this way means you won’t get an official time but you will get a finisher award.

  • Liz says:

    Could this course be for first time half-marathon runners since there is no “regular” half and only the trail? If running with someone, is it possible to still run with them on this trail? Thank you!

    • Kaelee Clifford says:

      Hi Liz – First time half marathon runners can run this course, just be sure that you are properly trained for the distance and terrain (mostly sand with some minor climbs). You can run with a partner on this course but will need to go single file at times. Find the course description here:

  • Walter Strach III says:

    Is there a waiting list for the 50 mile or 55k? My wife and daughter want to run the 1/2 marathon but I don’t want to register them if there is no event for me. Would have signed up sooner but have been running in the Grand Canyon and Brice Canyon the last couple of weeks.



    • Kaelee Clifford says:

      Hi Walt – Unfortunately, there is not a waitlist for this event. Your best bet to get into the race is to try to buy a bib from another runner who cannot make it.

  • Susanna Hawkins says:

    Hello, I am interested in signing up for the 100 miler. How many entrants do you take so I can watch the list as it fills? Also how quickly does camping at the start fill up?

    • Kaelee Clifford says:

      Hi Susanna – The 100-miler doesn’t usually sell out – there is a 300 runner cap that we most likely won’t reach.

  • Shannon says:

    ISO: 50 Mile race entry(s). Looking for someone that would like to transfer their 50 Mile bib (or 2 of them for 2 different people!)
    Thank you, Shannon (Aug 3rd, 2018).

  • kimmy j says:


    How does one apply for any job openings with vacation races or Antelope Canyon Ultra Marathons?

  • Catherine says:

    How can I find someone who wants to transfer a bib?

    • Kaelee Clifford says:

      Hi Catherine – We suggest posting on our Facebook page, Ultra Adventures. We usually see bibs for sale once refunds are no longer available – December 17th.

    • Natasha says:

      Catherine – what is the distance that you are looking to transfer?

      • Sam says:

        I’m looking for a half marathon bib, if you happen to have one you’d be willing to part with! Racing with a friend who is already registered.

  • Steve Yob says:

    I am in the half with Lynn McDaniel. I am also trying to do the 50 states which require a marathon distance. I did not think you would fill up this quickly. Can I run a longer distance to get this done as one of my states? I would be greatly appreciative it.

    • Kaelee Clifford says:

      Hi Steve – You can register for the 100-mile event and then only run 50 miles or 55k. Doing it this way means you will get a finisher award but not an official time, as you would have dropped from the distance you registered for.

  • Sarah Ottosen says:

    Does the half marathon have any portion that’s down inside the canons, or is that only for the further distances?

  • Lauren Smith says:

    What mile/pace are grim reaper cutoffs in 50 miler for Antelope Canyon

  • Kelsey says:

    If you only do the half marathon do you get to see all the places shown in the video? And do you get to run through the canyons as shown?

  • Jaime says:

    Wondering if I register for the 100M if I can transfer to 50M if needed? Thanks

    • Kaelee Clifford says:

      Hi Jaime – If the 50-miler wasn’t sold out that would be a possibility, but because it’s sold out you cannot. You can drop distance during the race if needed. You will qualify for a finisher award for the farthest distance completed but with will get a DNF for the original 100-mile distance.

  • Linda Scott says:

    Is there a training program for this race?

    • Kaelee Clifford says:

      Hi Linda – We do not offer a specific training program for this event.

  • Anthony says:

    At what point can pacers join the 100 mile race?

    • Kaelee Clifford says:

      Hi Anthony – Pacers can join their runners at Horseshoe Bend aid station. Paces have to take the shuttle there, as there is no parking at that aid station.

  • Claudie Leece says:

    What is the time limit on the Half Marathon?

    • Kaelee Clifford says:

      Hi Claudie – There is a 4-hour time cutoff for the half marathon.

  • Tara says:

    I will be in the area at the same time as the Antelope Canyon Marathon 2019. I am a runner, but do not plan to do this event. I do plan to visit the Canyon and do not want to be in the madness of race prep when visiting. Can you tell me when set up begins for the trail? I may decide to adjust the time of my visit. Thank you!!

    • Kaelee Clifford says:

      Hi Tara – The trails will be marked Wednesday before the race. You should run into too much madness with the trail marking and race set up.

  • Russell Herman says:

    For the Antelope Canyon 100 miler, at what mile can a pacer jump in?

    • Kaelee Clifford says:

      Hi Russell – Pacers can join at Horseshoe Bend aid station but you must take the shuttle – there is no parking at that aid station.

  • Susan Sanders says:

    Hi, my name is Susan Sanders. I got an email indicating I can still register for the 34 mile run. I might have deleted it. It was a ticket to confirm I can still register. Please help me find it. Susan Sanders AKA Susan Yellowhair or Harper.

  • Jessica Anthony says:

    Can you walk the race 1/2 Marathon Antelope canyon. ?

    • Kaelee Clifford says:

      Hi Jessica – You can walk the half marathon, just be aware of the 5-hour time limit.

  • Norberto Roman says:

    Question? What’s the process if I decide to ask for a refund? I might not be able to race, don’t know yet based on the doctors decision.

      • Andrew says:

        Kaelee, are we able to purchase other people’s bibs? If so, Noberto, I will buy your bib if this is allowable.

        • Kaelee Clifford says:

          Hi Andrew – Yes, you can buy another runner’s bib by following these instructions:

      • Sam says:

        After refunds are processed, will those bibs be offered on the website again? Or only at the expo?

        • Kaelee Clifford says:

          Hi Sam – Registration is actually oversold based on historical data for refunds/transfers/deferments, so those bibs are not made available.

    • Derrick Searle says:

      I am interested in buying a 50 mile bib. If you are unfortunately unable to run, and you are signed up for the 50 mile, I would Gladly pay you full price.

    • kristen says:

      Norberto, I am looking for 50k or even half marathon bib. If you aren’t able to run and would like to sell/transfer it, I would like it! Please let me know and I hope you recover and able to run very quickly!

  • Andrew says:

    Hello, is there waitlist or exchange to purchase bibs?

    • Kaelee Clifford says:

      Hi Andrew – There is not a waitlist for this event. Your best bet to get into the race is to try to buy a bib from another runner who cannot make it. The best place to find runners selling their bibs is on the event page on our Vacation Races Facebook page.

  • Sam says:

    I promised a friend I’d run the half with her, but didn’t get my bib before it sold out. I have tried looking for a half bib, and someone has offered me a 50K bib. Would you allow us to transfer the 50K bib to me, and then downgrade it to a half bib?

    • Kaelee Clifford says:

      Hi Sam – Bibs can be transferred to another runner by following these instructions:
      1. Sign In to RunSignUp
      2. Go to your Profile
      3. Click Manage Registration next to the registration that you would like to transfer to another person
      4. Click the Transfer To Another Runner menu item
      5. Fill out all required fields
      6. Select either Transfer as a Gift or Transfer for Refund

      The half marathon distance is sold out as well so you won’t be able to transfer to that distance officially, but you can run that distance and get a finisher award but you will get DNF as your official time for the 50k distance.

    • kristen says:

      Hey Sam , did you end up getting this bib? If not and its still available I would REALLY like to get the 50k bib! Please please please let me know :) thank you!

  • Robert Szmanda says:

    Hello to those already registered for the Antelope Canyon 50 mile ultra. My wife (Jill Bartlett) is registered, however I was a knucklehead and waited until it was sold out. I would like to purchase your bib if you are unable to use yours. Please email me if interested. In the meantime I will be training with hope!
    Thanks for the consideration.

  • Stephanie says:

    Hi. I read that you had to check in at aid all aid stations or risk being disqualified. Does that apply to the half marathon as well? Or just the longer distances?

    • Kaelee Clifford says:

      Hi Stephanie – That does not apply to the half marathon, just the longer distances.

  • Sheryl Hiemstra says:

    Just see now there is no wait list…so anyone out there with a 50 mile bib they are looking to transfer – please let me know! Thanks.

  • Geoff Sage says:

    Is there anyway to get a gpx or tcx file of the 50 mile course? Thank you!
