Buffalo Bicycle Classic

About the Event

Join us for the Elevations Credit Union Buffalo Bicycle Classic on Sunday September 13, 2026.  This ride has 9 different courses for riders of all abilities, including the family-friendly Little Buff.  The Boulder Canyon will be closed westbound for the Epic, Epic 75 and the beginning of the Gravel Epic for riders to enjoy a safe beautiful ride.  GRAVEL RIDES:  the Gravel Epic, a 60 mile gravel ride that goes up Magnolia Road to Nederland then Peak to Peak Highway to Gold Hill and back to campus. But only if you are buff enough! The 44 mile Gravel Buff heads north toward Hygiene along gravel roads along the way.     

The Buffalo Bicycle Classic has always been more than just a bike ride, it is also the largest scholarship fundraising event in the State of Colorado. The BBC scholarship fund raises money to support high-achieving, Colorado high school graduates in their academic pursuits at CU Boulder. Over 430 Buffalo Bicycle Classic scholars have graduated from University of Colorado.  Register or make a donation and change lives!
