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 with a 1.8 mile shortcut for kids. Run in the Dog Wave and get your dog a race bandana! Your chance to be a part of marathon weekend – at a much shorter distance!

We are excited to have our  5K course Start and Finish at the Marathon Start and Finish Line! The course wraps around City Park and Ferril Lake with terrific views of downtown and the mountains.   The adjusted course map (new for 2017) with this new Start Line will be posted pre-race.
