Race Details
Get ready for an awesome adventure race in the wilds of the Teton region! For 2026 we plan to host an 8hr race (bike and trek), and a 26hr race (bike, trek, and class I-II pack rafting). More info to come as planning and permitting comes together!
Our 8hr race is a great day-long challenge, for those who newer to adventure racing or those not wanting to race through the night.
Our 26hr race is an ultra-endurance challenge that will push you to your limits and beyond. While we welcome those new to adventure racing, we ask that racers have prior navigation experience (or a willingness to practice and learn prior to race day), as well as the fitness to travel long distances over difficult terrain at altitude and a willingness to suffer. 🙂 If you are a beginner and are considering the 26hr Ogre, please feel free to reach out to us and ask questions so you know what you are getting into.
Below you will find race information such as team categories, schedule, race distance estimates, camping/lodging info, and more. Make sure to also check out the Gear List for required gear and other gear-related information.
