Estes Park ~ Georgetown to Idaho Springs ~ Ned*Ned

We invite you (back to the mountains) to join us for three of Colorado’s original and most beloved half marathons for the 5th annual Colorado Mountain Half Marathon Series! 

Your safety is our number one priority.  All events have full COVID-19 mitigation plans in place. While the events will have some differences for safety, we will still be delivering the most epic beautiful scenery.  

Start your journey on June 20th with the Estes Park Half Marathon, part of the Estes Park Marathon 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, plus the 90% all downhill course will get you a super-fast time!!!

Next test your speed and go after a new PR with one of Colorado’s oldest half marathons, the 43rd 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 NedNed 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.

If you can’t join us for the whole series this season, we invite you to join us at any of the individual events using the following links!
