Three Creeks Half Marathon
The Three Creeks Half Marathon is an annual running event held at Cherry Creek State Park in Englewood, Colorado. The 2026 edition marks the 13th anniversary of the race. The course is designed to be flat and fast, featuring a total elevation gain of 291 feet over the duration of the race.
Participants travel through various sections of the state park, following the banks of Cherry Creek, Windmill Creek, and Cottonwood Creek. The terrain consists of a mix of surfaces, including roads, paved running trails, and wide dirt trails.
The event offers two primary registration options:
- 13.1 Miles: An individual half marathon distance.
- 13.1 Miles Relay: A two-person relay splitting the course into two 6.55-mile segments.
For those participating in the relay, a shuttle van is provided to transport second-half runners to the exchange zone and return first-half runners to the start and finish area. The event is organized by Racing Underground and takes place in April within the natural surroundings of the park. Visit the organization's website for the most recent information.
