Roo Last Man Standing

ROO Last Man Standing

ROO Last Man Standing is a backyard ultra held on nearly 2,000 acres of private ranch land at Ponderosa Ranch in Clancy, Montana, with the race hub at Dutchman Creek Events Center. The property sits at the edge of the Elkhorn Mountains and the course offers ranch roads and trail terrain with expansive views.

The event follows the classic Last Man Standing format. Every hour runners start a 4.2 mile loop; completing the loop within the hour allows a runner to start the next one. Finish a loop early to use the remaining time to rest. Miss the next start or fail to finish within the hour and that runner is out. The race continues until a single runner completes one final loop alone. There is no fixed distance or overall time limit.

The last runner standing receives a $10,000 prize. Each runner may have up to four crew members and a designated crew area is provided for small tents, chairs, coolers, and personal support stations. Some race supplies may be available, but runners are responsible for bringing sufficient food, hydration, and gear for the event duration.

The format emphasizes endurance and pacing, with the race progressing loop by loop through day and night as runners continue until only one remains. Visit the organization's website for the most recent information.
