Racing Underground brings you an amazing half marathon this spring! The Three Creeks Half Marathon features a half marathon course that is flat, fast and scenic!
Travel on foot through some of the most beautiful parts of Cherry Creek State Park, with a total combined elevation gain of only 291 feet spread out over 13.1 miles as the course follows the banks of Cherry Creek, Windmill Creek, and Cottonwood Creek on a mix of road, paved running trail, and wide dirt trails.
We hope to see you at the 13th annual Three Creeks Half this April!

BACK IN 2026 - 2-person Half Marathon Relay!!! Each team member runs half of the course. The exchange zone is at the 6.5 mile aid station. A shuttle van will transport all runners who are running the second half of the course to the exchange zone and will drive all first half runners back to the start/finish line. All team members will receive a gender-specific race shirt, free race photo downloads, tasty quesadillas fresh off the griddle, and a finisher medal with the option to have the back engraved for free! Awards will be presented to the first place male, female, and co-ed teams. For planning purposes, the second half of the course has slightly more uphill than the first.
