The Experience
The Rocky Mountain Half Marathon & 5K, now in its 16th edition, takes runners through the heart of Estes Park with breathtaking views of the Rockies. The course, set at high altitude, delivers crisp mountain air and a challenging yet scenic route. With a median field of about 2,100 runners, the race has a lively community feel.
Recent years have seen around 900 finishers, with a 5% repeat-runner rate—testament to the race's enduring appeal. The competitive front runners clock times around 77:25, while back-of-pack runners savor the mountainscape. The event also offers a 5K and an 'Elk Double' for those seeking extra miles and a special medal.
Post-race, runners collect their shirts and enjoy the festive atmosphere in Estes Park, a gateway to Rocky Mountain National Park. The combination of stunning scenery, small-town charm, and a well-supported course makes this a destination-worthy race.
