26.2 Marathon

Run through Denver’s best landmarks in the 15th Anniversary Colfax Marathon!  Run through the home of the Denver Broncos – Empower Field at Mile High – twice!  Run along 7 miles of water including Confluence Park, Cherry Creek, the Platte and Sloan’s Lake, through Denver Fire Station #1, through downtown Denver and onto America’s longest main street, Colfax Avenue – all under the majestic views of Colorado’s Rocky Mountains.

Marathon Relay

What’s better than running 26.2 miles through the Mile High City?  Sharing the miles with friends!  Get a team of five to run Denver’s only 26.2 mile Marathon Relay.  We have 3 divisions in the Relay: Open (keep reading), Corporate (employee teams), and Government (employee teams).  See the great sites of the Mile High City on each leg – from Empower Field at Mile High to the Confluence, Sloan’s Lake, downtown, or the neighborhoods around Colfax – which one will you run?  The relay sells out almost every year!!

Half Marathon

New this year, you’ll experience vibrant Colfax with iconic spots like VooDoo Donuts, Irish Snug, and Cathedral Basilica.  The new course also takes you by the Capitol, Civic Center Park, 16th Street Mall, Convention Center, stellar Colorado mountain views, and the Cherry Creek Bike Path.  While you’re running through downtown, you’ll run through Denver Fire Station #1 and get high-fives by a row of firefighters.  This is the only race in the country with a fire station run-through!

Urban 10 Miler

Colorado’s 10-mile race runs the final miles of the marathon course through Empower Field at Mile High, Confluence and downtown!  Start on the Rocky Mountain College of Art & Design campus, finish in City Park.  Spots are limited and this race has sold out in several years.

Big After Party!

Colorado renowned band headlines the awesome afterparty and Beer Garden lakeside in City Park!  Free beer by Michelob Ultra as well as lunch.  Runners can meet up with their friends, family and fellow runners to show off their finisher medals and enjoy the spring day.  Meet up with your running clubs at their tents.  Charity Partners each have a blue tent in Charity Partner Village, so make sure to stop and say hello.  Our runners say it best:

“I’ve done the Colfax Marathon 3 years in a row, this was the best post-race party yet!  Great job, and thanks!“
