DENVER — Colorado's largest running event is four months away and Wednesday is the final day to register with early season pricing.
The Denver Colfax Marathon presented by Cigna returns Saturday, May 20, and Sunday, May 21, 2023. The weekend's events include a marathon, half marathon, 10 miler, 5K and the nation’s largest marathon relay.
Wednesday, Jan. 25, at 11:59 p.m. is the last chance to register to take advantage of early season pricing. Depending on what race you run, you could save up to $70 on registration fees compared to race week pricing.
More than 20,000 runners are expected to participate in the 17th annual Denver Colfax Marathon, which will again serve as a Boston Marathon-qualifying event.
The marathon travels through Denver's City Park, Denver Fire Station No. 1, Empower Field at Mile High and Sloan Lake. The half marathon traverses through Denver Zoo.
