The 2026 BOLDERBoulder returns on Memorial Day, Monday May 25th!

There is a lot more to the day than the 10K. It’s part run, walk, parade, costume party, professional race, expo, and it ends with the largest Memorial Day Tribute in the country inside the University of Colorado’s Folsom Field. We’d love to invite you to stay for the afternoon or the whole weekend to take full advantage of everything beautiful Boulder, CO has to offer.
