🏇 Race Categories:

• BAREBACK: This race can be run "bareback" style (general indoor transition area with no aid station access, just water and bathroom access). It’s cheap, but great for those who can and want to take care of themselves, but still race. $55 Registration fee during the early bird pricing. Then it's $65.
• THOROUGHBRED: Deluxe Aid Station with Catered Food, Reserved Indoor Transition Area, Custom Dizzy Horse Hoodie, or several options in between that you can add on as you wish.
• Equal Footing: Regardless of whether you go Bareback or full-on Thoroughbred, once the top of the hour starts, everyone runs the 4.167 miles through the course.

🏁 Start Corral:

The Start Corral will be just outside the Bonneville County Exhibition Hall. You’ll need to be in it before the top of each hour. At the top of each hour, you’ll start off on a wandering and possibly dizzying journey through Sandy Downs Park...

🏆 The Race Progress:

At the start of each lap, everyone who remains is tied for first. The race continues until only one participant remains. The Last Horse Standing must complete one more loop than 2nd place (the assist person). Everyone who doesn’t win will get a custom DNF award...

🍽️ Deluxe Aid Station:

The Deluxe aid station will be right inside the Exhibition Hall and have specialty items for food along with standard aid station fare...

🤝 Crew:

While the runners are out running the course, crew can refuel and relax. Eliminated runners are welcome to stay and “join” as crew for runners still in the mix. Crew may only set up chairs in your reserved booth 10x10 area...

🌟 The Vibe:

It is a great social race that also requires strategy, a strong will, and a determination to not quit. The first several hours of the race are incredibly social...

🎉 Sponsors:

We are excited to have the support of Grit League, the Idaho Falls Trail Runners, Teton Auto Group, Idaho Falls Marathon, Spitfire Ultra Trail Challenge, and LiveTrackingCentral.com in making this an event that you won’t forget.

🙋‍♂️ Volunteer:

If you don’t want to run but are willing to volunteer, we’d love to have your help. Please sign up to volunteer. Depending on how long you commit, volunteer perks can include access to the Deluxe Aid Station, a T-Shirt or Hoodie, and/or future entry into the event.
