Boulder: A Cycling & Endurance-Sports Capital

Published June 2026 · Updated July 2026

Boulder isn't just outdoorsy — it's one of the world's endurance-sport capitals, a magnet for professional and Olympic cyclists, runners, and triathletes.

The BolderBOULDER

On Memorial Day, the BolderBOULDER 10K sends tens of thousands of runners through the city to a finish inside CU's Folsom Field — one of the largest road races in the U.S., with an elite pro field and a big Memorial Day tribute. BolderBOULDER.
