Who Can Race?

Our events are designed for anyone interested in experiencing an epic outdoor adventure…who can meet the physical demands of running, biking and paddling for several hours at a time.

No specific level of skill or experience in any one discipline is required, however, a little mental toughness goes a long way. Event goes on rain or shine. Novice athletes will find the course challenging and exhilarating but are able to move at their own pace based on their personal fitness level.

More experienced athletes and competitive racers will experience the race in an entirely different way as they test themselves to complete the course with the fastest time.

What age do I have to be to sign up?

 18+ to race as a solo. 15+ if you race on a team with a parent or guardian. (18+ for the 30hr race)

What is the course breakdown by discipline?

See the event details for each race. Disciplines, Distance, Difficulty and Elevations Profiles will be given to you as a range for training purposes. The exact course is disclosed at racer check-in, the night before the race.

Do I have to know how to navigate by map and compass?

Topo maps along with UTM grids are given to you at racer check-in. Teams will plot the Check Points (CP’s) for the race. You will then choose your desired route from CP to CP. So basic map navigation is needed, but most teams do not need a compass except for specific orienteering courses within the race. The Buena Vista race has a specific leg of the race that is orienteering based.

Is GPS allowed?

Yes. We will allow a GPS but you should be comfortable navigating with a topo map.
