What is the Colorado Mountain Half Marathon Series?

RUN YOUR TRANQUILITY

 

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, along with HAL Sports and RunningDenver.com to create the Colorado Half Mountain Marathon Series so you can  Run Among the Peaks! 

 

It all starts on June 20th 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 42nd Annual Georgetown to Idaho Springs Half Marathon (known as GTIS Half) takes place on August 14th. You start at beautiful Georgetown Lake between towering Rocky Mountains as you cruise through what is mostly downhill and fast course into iconic Idaho Springs. 

 

The series wraps up with the Ned*Ned Half Marathon in Nederland on September 11th. 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.
