Race Results

CR Half Marathon 

Half Marathon
Our small-Town character with wide open spaces make Castle Rock a great place to run. Runners will start Downtown, then tour the Town before retreating to the East Plum Creek Trail for a shady run by the creek. The Half Marathon is a scenic run with nominal elevation gains and losses. Most of the course stretches along the serene untouched open space of Plum Creek.

Not up for a traditional 13.1?
The shorter 5-Mile race follows the best parts of the Half Marathon but cuts the distance. Midway between a 5K and 10K, you'll love this run.

Ready for a challenge?
We are also proud to present the Rock Challenge for the most adventurous runners. This race adds the steep ascent and descent of our iconic Town monument, the Rock, to the first half of the 5-mile distance, making it a thigh-burning wake up call.

All three events will be professionally timed, with prizes for top finishers. Registration spaces are limited so don't wait to sign up.

A post race expo, unique downtown boutiques, and hometown restaurants are all within a few blocks of the start / finish - make this a great day to spend in Castle Rock.
