Best Half Marathons In Wyoming – Runner’s Choose Wyoming’s Top Half Marathons

Wyoming is the nation’s least populous state. Weather can be harsh and unpredictable in the Cowboy State. But if you are up for a challenge, some of the nation’s most scenic half marathons take place here.

Star Valley Half Marathon - Thayne

The Star Valley Half Marathon is a USTAF sanctioned event and possibly the most scenic race in America. There a mountains in literally every direction. The race commemorates the life of Jeremy Bart Kunz, a local runner, who was killed by a drunk driver in 2009. Proceeds from the event benefit local families in need.

The Course​

This is a great course if your looking to set a PR. It mostly follows paved roads and is almost exclusively downhill. Four aide stations are spread throughout the race at miles 3, 6, 8.5, and 11 with post race snacks at the end. While the race is well supported, the local communities are small, so no big crowds at this one. Learn more about the course here.


"The Star Valley Half has a beautiful course, family friendly atmosphere, accommodating staff, great recovery snacks, cool bling and shirts. What more can you ask for. It's a must run!" - Annai Rob Smith, review

"Beautiful course! It's a family that puts together this race with the support of the small, local community, and they do an amazing job. You'll get cheered on by the locals as well as the cows in the fields you run past. I enjoyed every minute of the race, including the awesome post-race snacks. Great swag bag and sweet medals too!" - Jill Williams, Review

Grand Teton Half Marathon - Jackson Hole

This event takes place just outside Grand Teton National Forrest. Come appreciate some of the most beautiful sights that Wyoming has to offer while running in this half marathon. Get registered here.

The Course​

This is point to point event jumps between paved and gravel surfaces. The race starts out pretty flat for the first 4.5 miles, but from there on, the course starts running uphill all the way to the finish line. Bare in mind that that this is cup free event. You will be provided with a hydrapouch before the race or you can bring your own bottle.


"Loved the race pouches I wish more races used those so you don't have that mess of wasted paper cups. It's a genius idea and the pouch itself isn't difficult to carry around the course."
- Heather,  Runner Review​

"Great race! Beautiful scenery. Liked food, t-shirt, and really liked medal. My first medal and I love it!" - Mary, Runner Review​

While not being a huge race, this is one of the most popular half marathons in Wyoming. According to, it's a "race with all the amenities of a larger race but without the crowds." Click here for dates and registration info. 

The Course​

This race is a point to point course that runs along side the Platte river. The course is pave and features ample water stations placed almost every mile. The race is mostly flat and downhill, so it's a pretty quick run.


"The course was challenging with a diversity of scenery. We ran some river trail (paved and some dirt due to river flooding, road and around a golf course). I've run about 15 1/2 marathons and one full and countless smaller races. The volunteers were so friendly and the atmosphere was so upbeat. The food at the end was magnificent. The host hotel was very close to the starting line and it was easy to get to." - Nan O'Neill, Review​

"Everything from the host hotel and pasta dinner to the finish line and post-race food was excellent. The spacious indoor facilities at the start were much appreciated (especially on a cool and windy morning). The "Run with the Herd" logo for the race had extra meaning as a group of pronghorns ran between runners shortly after the start. Much of the course was along a scenic asphalt bike path next to the Platte River. Fluid stations were frequent and staffed by enthusiastic volunteers. The shirts were high quality and the finisher medals and award winner fleece vests were extra special." - J.M., Review​

Jackson Hole Half Marathon

This is another great race in Jackson that you won't regret running. Race organizers say, "take up the challenge and prepare yourself now. Because if the elevation doesn’t take your breath away, the incredible scenery will." Find out more on their website.

The Course​

This point to point race takes place on a USTAF certified course. According to the race website, "You’ll follow a path that is a fast, net downhill route that has been described as one of the best altitude courses in the nation."  Water stations are located about every 2.5 - 3 miles.

"If you love small races in beautiful places, this one is for you! The only downfall may be the weather- it varies from year to year. Expect anything!" - Review​

"The course takes you from Teton Village to Jackson Hole, so of course the views are amazing. I believe it is net downhill. The volunteers were fantastic and enthusiastic, particularly at the end, where there was food and drink waiting, along with medals." - Kira H., Review​
