A grassroots 12 hour mountain bike race. 3rd year as a 12 hour race - 7th year for race venue. Race time is 7 AM to 7 PM. 100% of the race proceeds benefit Montezuma County Partners, a local, 501(c)3 non-profit, organization that has been mentoring at-risk youth for 17 years.
Racers will ride on a stellar network of singletrack known as Phil's World - in the shadow of Mesa Verde. The race course twists and turns through juniper trees, intermittent technical spots, and fast descents. The trail will be marked the week before the race. Area maps are available at from Big Loop Maps or at Kokopelli Bike & Board
The 12 hours of Mesa Verde is staged at the Montezuma County Fairgrounds in Cortez, Colorado which is in the southwest corner of Colorado (40 minutes from Durango).
