About the race
The race across the sky. 100 out-and-back miles above 10,000 ft in the Colorado Rockies. Second Saturday in August.
Typical weather
August is peak summer. Heat and humidity are the variable that matters most; pacing and hydration for temperature can decide your day.
Who it favors
Mountain biking favours riders with handling and repeatable power. Time is won and lost in the technical sections and short, sharp climbs, not in smooth steady efforts.
