The YMCA of Boulder Valley pioneered biking in Boulder County through the Y Riders program more than 25 years ago, and we celebrate that great success every year. Our unique Y Riders programs provide progressive biking courses for everyone—from kids who are learning to conquer a two wheeler to teens biking off road and through mountain trails. Small groups with low participant-to-staff ratios provide the perfect environment for riders to learn safe biking and to build their skills. Our staff has extensive experience in biking and is committed to supporting our cycling community.

There are no clinics offered at this time. Check out Y Riders Cycling Summer Camps.
