Buffalo Bicycle Classic
About this race
Join us for the Elevations Credit Union Buffalo Bicycle Classic on Sunday, September 13, 2026! Choose from nine unique ride options designed for every type of cyclist. Our road courses range from moderate rolling routes to the challenging Epic climbs. For dirt‑lovers, our gravel courses offer everything from long, demanding mountain gravel to scenic mid‑distance routes. And for families and newer riders, the Little Buff provides a fun, easy ride on car‑free bike paths.
Ride Boulder Canyon on one of the Epic courses: If you’re riding the Epic, Epic 75, or starting the Gravel Epic, you’ll experience something truly special: westbound Boulder Canyon will be closed to vehicle traffic from 7–9 a.m. This is the one day all year when cyclists can enjoy this stunning canyon completely car‑free—an unforgettable perk reserved just for Buffalo Bicycle Classic riders.
Help Us Fund the Future: The Buffalo Bicycle Classic is more than a ride—it’s a fundraising event dedicated to supporting Colorado students through the BBC Scholarship Fund. This year marks our 24th anniversary, and our mission remains clear: help high‑achieving, high‑need students access a CU Boulder education.
Your registration supports scholarships—but you can make an even bigger impact by raising funds for BBC scholarships. As a part of ride registration, you have the option to become a fundraiser and collect awesome swag along the way. We will create a custom page and you can invite friends and family to contribute, and help open doors for more students. Every contribution fuels opportunity. Since 2003, the Buffalo Bicycle Classic has raised $4.3 million, helping 450+ students pursue their degrees. Your support ensures these scholars can focus on their education—not their tuition bills. Every registration counts. Every fundraiser amplifies the mission. Every dollar changes lives.
RIDE BIKES. CHANGE LIVES.
The Buffalo Bicycle Classic brings an exciting Ultra, 22.5K to Boulder, Colorado on September 11, 2022. Don't miss this beautiful event!
