Race Weekend Schedule


2pm-7pm - 100, 50, 55k and Half Marathon check-in at the race expo which will be located at the Community Townhouse at John C Page Park. 

(Previously the expo was going to be at the Page Shores Amphitheater, but we’ve moved the expo location to the Community Townhouse at the park because Friday will be pretty cold (it might even snow) so we're hoping to keep you a little warmer on Friday.)

Race Expo Location


5am - Last minute check-in opens
6:00 am - 100 mile & 50 mile Start
7:00 am - 55K Start
8:00 am - Half Marathon Start
12:00 pm - Half Marathon Time Limit
6:00 pm - 55K Time Limit
9:00 pm - 50 Mile Time Limit


Noon - 100 Mile Finish

*All Distances Start and Finish at the slickrock 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.

For the 100 mile and 50 mile distances there are two “Grim Reaper” check points 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.

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

Minimum Pace Times

100 mile - 30 hours
50 mile - 15 hours
55 K - 11 hours
Half Marathon - 4 hours

Aid Station Info

The 100 miler will pass through 21 fully stocked aid stations.

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 50 miler has 10 aid stations.
The 55K has 8 aid stations.
The Trail Half Marathon has 2 aid stations.

Here is a tentative list of items that may be found in aid stations: water, an electrolyte, fresh cut fruit, several salty items and several sweet items, and soda. Aid stations later 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, first aid supplies.  We will have a limited supply of gels, salt caps, and electrolyte caps. Remember this list is subject to change.

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.

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.  Guests can book online or call 1-800-528-6154.

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.
