Kick off Denver’s Colfax Marathon weekend in City Park with the Bellco Colfax 5K! Go for a PR in this chip-timed race. Separate stroller-friendly start wave for families and walkers. Run in the dog wave and get your dog a race bandana! Post-event party with food and live music. A great chance to be a part of marathon weekend – at a much shorter distance!
Run an individual race on Sunday and the 5K on Saturday, and you'll receive our Colfax 2 Day Mile High Challenge medal as well as your Sunday medal!
