Rock ‘n’ Roll Denver Half Marathon, 10K & 5K

Sunday, October 18, 2020 • Denver, CO • Course Map

Note: The 2020 event has been cancelled.

A loop course through the city that starts and finishes in front of the Colorado State Capitol building — and includes stretches around Coors Field and the Pepsi Center, where Denver’s MLB and NBA teams play — awaits runners at the Rock ‘n’ Roll Denver Half Marathon, 10K & 5K, which saw more than 12,000 runners and walkers cross the finish line last year.

More than 8,000 of those finishers competed in the half marathon alone, a race that shows off many of the city’s many spacious parks as well as the scenery off in the distance — on a clear day, runners can see the snow-capped peaks of Colorado’s Rocky Mountains to the west.

The course for the half marathon follows an out-and-back loop route that starts at Civic Center Park in downtown Denver. From there, the half marathon course takes runners first in a northwest direction away from the park, along 14th Street on the way toward the Pepsi Center, the home arena for the NBA’s Denver Nuggets and the NHL’s Denver Avalanche.

After the run past the arena, the course next takes runners up Blake Street past Coors Field, where Major League Baseball’s Colorado Rockies play every summer. After runners make the turn there, they make a few more turns on Wazee, 15th, Market, 19th, 20th, & Lincoln Streets before heading over onto the long straightaway along East 17th Avenue.

From there, the race will take runners on a route that heads all the way east toward City Park, where runners will make their way through the park and around Ferril Lake on three sides before continuing along East 17th Avenue. Runners will reach a turnaround point at Colorado Boulevard, after which the course continues along East 17th Avenue before reaching the finish line back at Civic Center Park.

Runners will have a 4-hour course time limit for the half marathon.

    My name is Dr. Riley Kulm and I’m a chiropractor and sports medicine doctor based in Aurora. I heard about your race from a runner I was treating during a Runner’s Roost Run Club last week. I specialize in the treatment of runners and would love the opportunity to provide some complementary injury consultations, functional movements exams, gait analyses, and active release technique (ART) treatments at your race. I’ve worked multiple marathons and triathlons in the past and the athletes are some of my favorite to work with. Thank you in advance!
