The Go Fast! 24 Hours of Erock is Colorado’s only front range 24 hour mountain bike solo & team relay race. Offering recreational and competitive cyclists the opportunity to experience the thrill of competing in a challenging endurance race on a less technical off-road course. It all takes place at Douglas County’s beautiful Greenland Open Space, just down the road from the Palmer Divide (14 miles south of Castle Rock on I-25-exit 167).
