Get some fresh air. Escape to the mountains! With the Rocky Mountain Half Marathon, 5K, and Elk Double (half + 5K) you can choose your own adventure!

Planning Your Trip

The Race Expo, Start Line, and Finish Line will be by the lake at the fairgrounds in Estes Park, Colorado! Both courses are scenic runs with gorgeous views of Estes Park and the Rocky Mountains.

Race Overview

The Rocky Mountain Half Marathon and 5K courses both take place just outside Rocky Mountain National Park and start and end by the lake at the fairgrounds in historic Estes Park, Colorado!

You'll have plenty of space at the fairgrounds for parking and runner drop-off/pick-up. 

On course expect about 6 cup-free aid stations on course stocked with toilets, water, Gnarly electrolyte drink, and Honey Stinger gels.

Travel Overview

If you're flying here your option is pretty much Denver International Airport (DEN). Plan on about 2 hours to drive to Estes Park from the airport.

Explore the Park

Rocky Mountain National Park in northern Colorado spans the Continental Divide and encompasses protected mountains, forests and alpine tundra. It's known for the Trail Ridge Road and the Old Fall River Road, drives that pass aspen trees and rivers. The Keyhole Route, a climb crossing vertical rock faces, leads up Longs Peak, the park’s tallest mountain. A trail surrounding Bear Lake offers views of the peaks.

Free Training
