The Races

Marathon: This incredible 26.2 mile course runs through Sports Authority Field at Mile High, along 7 miles of rivers, lakes and bridges, and of course takes place on America’s most famous main street – Colfax!

Half-Marathon: Fast, flat and fun – one mile of this run even treks through the Denver Zoo! This race works for runners or walkers, but the number of entries is limited, so register early!

Marathon Relay: Five individuals take on 26.2 miles as a team, each running distances between 3.9 and 6.4 miles. Walkers are welcome in this race, but your team cannot consist of only walkers.

Urban 10-Mile: Trek 10 miles through Denver’s urban jungle! This event begins in Lakewood and uses the marathon course to finish at City Park.

Bellco Colfax 5K: This Saturday event is for all runners, families and walkers who want a shorter course (there’s even a shortcut for those who want an even shorter distance!). The course stays in City Park and includes dog-friendly and stroller-friendly waves!
