Welcome to Denver's Best Spring Half Marathon!
Saturday April 1, 2023 at Cherry Creek State Park
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 9th annual Three Creeks Half this April!
