Celebrating its 25th year, The Subaru Elephant Rock Cycling Festival is the unofficial start to the Colorado cycling season. Whether you want to crank out an early season century, spin with your kids on the 7-mile family course or tune up the legs with something in between there is a course for cyclists of all abilities. All of the rides start and finish at The Douglas County Fair Grounds in Castle Rock.

After a day in the saddle, enjoy the Party at the Rock post-ride picnic and cycling expo.
