Colorado Mountain Half Marathon Series


June 17th *  August 11th * September 8th

We all love a Colorado original and we certainly love the beauty and tranquility of our mountains. Three of Colorado’s original and most beloved half marathons are teaming together- Estes Park Half Marathon, Georgetown to Idaho Springs and Ned * Ned- to create:

Colorado Mountain Half Series!

Run Among the Peaks and experience the beautiful seasons!

It all starts in June with the Estes Park Half Marathon, part of the Estes Park Marathon weekend with something for the entire family. Run the original in one of the most beautiful town landscapes known for its resident elk herd and the ever famous Stanley Hotel. All situated at the base of Rocky Mountain National Park.

Next test your speed and work to a new PR with one of Colorado’s oldest half marathons, the Annual Georgetown to Idaho Springs Half Marathon (known as GTIS Half) takes place in August. You start at beautiful Georgetown Lake between towering Rocky Mountains as you cruise through what is mostly a downhill and fast course into iconic Idaho Springs.

The series wraps up with the Ned*Ned Half Marathon in Nederland in September. Nederland is known for its amazing beauty and the world renowned Frozen Dead Guy (I know I have your attention now). It is nestled in a valley cut out by glaciers; you will run mostly on trails in beautiful national forests with Barker Reservoir as your backdrop.
