Course Details

Half Marathon Course Description

The half marathon starts promptly at 6:30 am on Saturday June 11th.

yellowstone elevation

The race will start and end at the Old Airport Road lot off Iris Street on the west edge of West Yellowstone. There is a ton of parking there and it is easy walking distance from many hotels on the south side of town.

The the majority of the race takes place on a dirt road and trail in Gallatin National Forest immediately southwest of West Yellowstone, MT.

The course starts flat but has a major and a minor hill that you need to train for. (See the map and elevation profile.) The best part of the course is that you will be less than a mile from the west park entrance.

Yellowstone Mile-by-Mile Description

Yellowstone Course Mile-by-mile!

  • The first three miles will be a loop, partially through town, and partially on trail just outside of town.
  • Miles 3-4 are pretty flat and straight as you head towards the hills.
  • At mile 5 is where it really starts to get pretty, and challenging. You run over a beautiful bridge that crosses the South Fork Madison River and really start to enter the forest.
  • Mile 6 is the most challenging section. You will start running uphill and in the 6th mile you will gain about 200 feet in elevation. Thick forest on either side. If you have to use bear spray it will be in this section (just kidding, but not really). You then start to flatten out and then enter a downhill.
  • The course gets more technical around mile 7 with some rocks and a less defined path. The course will be clearly marked, but those in the front will feel like you are running through some weeds.
  • Mile 8 is real fast down hill. Continues to be technical and weedy.
  • Mile 9-10 is downhill for bit an then starts to flatten out a bit as you enter some really beautiful area.
  • At mile 11 there is a slight hill that will feel big if you are not ready for it. Its only a 40-50 foot gain, but it's later in the race.
  • Mile 12 to the finish will be slightly downhill or flat.

The whole race is on a dirt road (depending on weather, there may be puddles). The path is a true trail with uneven ground and loose stones...please wear proper footwear and train accordingly!

Time limit
All runners will have 4 hours to finish the race. That is an 18 minute mile - plenty of time for walkers! If at anytime we deem it unsafe and need to pull a runner off the course we would hope for understanding and immediate cooperation. Failure to comply will result in being banned from future events.

Course Records
Our course record holders receive a FREE RACE ENTRY every year that their time remains the course record! The current course record holders are:
Male Overall: Samuel Stow  1:22:12 (2018)

Male Masters:

Female Masters:
Joanna White  1:37:52 (2021)

Aid Stations

Expect about 6 aid stations on the course at around mile 3, 5, 7, 9, 11, and 12. A medic will be stationed typically at the aid station at or near mile 9. Keep in mind, the exact location of each aid station may vary from race to race. Aid stations include toilets, water, Gnarly Hydrate, Honey Stinger gels, basic first aid supplies, and sometimes more. 

All stations are cup-free so plan to bring your own hydration solution or request a free HydraPouch when you register.

Race Expo & Bib Pickup

Bib Pickup Options

You have a couple of options for picking up your bib and race packet including at the race expo or we can mail it to you. When you register, we ask you to indicate when you plan to pick up your bib. If you plans change, don’t worry about it. We only ask to help us plan in terms of numbers.

Option #1: Race Expo (recommended)
Race expos are held the Friday before the race. They typically run 5-7 hours, allowing you to get your bib at your convenience. 

Option #2: Race Morning (not recommended)
We will have limited race morning packet pickup. We do not recommend waiting until the morning, but if it cannot be avoided - we understand.

Option #3: Shipped Before the Race
There is a cost of $30 if you want to have your bib and shirt mailed to you. We do this as a convenience for runners not wanting to drive to the area early. You can add a shipped bib to your registration until one month before the race by logging into RunSignup, clicking Manage Registration, and Add Ons.

Refunds: Once your package is shipped, you are officially checked in to the race and no longer qualify for our refund, deferment, or transfer options.

Race Expo

Location: Old Airport Road lot (off Iris Street)

Date: Friday, June 10th

Hours: TBD

This is a great opportunity to pick up your bib, check out the area, and meet fellow runners. We’ll have our merchandise table set up, so be sure to stop by and say hi!

Bring Your Own Bag
In our ongoing effort to eliminate waste during our races, our expos are bagless events. We encourage you to BYOB (bring your own bag) to hold your bib, race shirt, and any goodies you pick up from the race expo!

Race Day Schedule

The race starts at 6:30 am sharp at the Old Airport Road lot! We do not start our races late so please get to the start line early. Runners will have 4 hours to finish the race. That is a 18 minute mile- plenty of time for walkers!

Check back closer to the race for a comprehensive race schedule!

Parking & Staging


The race expo/bib pickup, start line, and finish line are all located at the Old Airport Road Lot off Iris Street in West Yellowstone. 

We will have plenty of parking to accommodate all of our runners, but please arrive early to avoid congestion. Most hotels are a short walk from the start line if you are staying in town and feel like walking. 

Parking will be in the Old Airport Road lot off Iris Street in West Yellowstone which is near the start line. We will have plenty of hot chocolate/coffee.

Camping is not allowed in the parking lot.

Runner Drop-off 

If you are dropping a runner off, please enter the parking area and drop your runner off just past the parking lot exit. This will allow cars parking to enter the parking area and avoid any traffic jams from runners being dropped off.


We expect to welcome spectators back to Yellowstone this year! 

You may park at Old Airport Road along with the runners and meet your runner at the finish line. Once your runner has crossed the finish line, please exit the runner recovery area to avoid crowding. The beverages, supplies, and medical tent at the finish line are for runner use only - thank you!

We recommend downloading the RaceJoy app to track your runner's progress and send them cheers along the way. Spend your morning in town and head to the finish line when they're close!

5K & Fun Run runners can pick up their bibs at the race expo before the race. Please plan to come early to avoid a last minute rush. 

Doubles & Grand Quad

What are the Doubles & Quad?

During the month of June we host four races on back-to-back weekends:

Weekend 1: Grand Teton Half Marathon + Grand Teton 5K (June 3-4, 2022)

Weekend 2: Yellowstone Half Marathon + Yellowstone 5K (June 10-11, 2022)

These races showcase the incredible beauty of Wyoming and Montana AND they are driving distance to each other! To give our runners an extra challenge (and an opportunity to keep exploring the parks), we've created a series of combination events. Our intrepid Double and Quad runners commit to running either a 5K + Half Marathon, 2 Half Marathons, or all 4 races in the span of one week!

Race Results and Photos
Race Results

Visit RunSignup for race results. Runner times are available ~20 minutes after you finish the race. Keep in mind, the results are not official until all runners have crossed the finish line, and have been reviewed by the event director. Because our age group winners are based on chip time, it is possible to cross the finish line before someone else in your age group while still finishing with a slower time than them. 

Top Finisher but missed the awards ceremony? You can request to have your place medal shipped to you!

Got questions about your placement? please email
