10K Races in Centennial, CO (2026)

Centennial is threaded through with greenbelts that make 6.2 miles feel like a tour rather than a grind. The High Line Canal, Cherry Creek State Park, and the creek trails that lace between neighborhood open spaces give everyday runs genuine variety - flatter canal stretches giving way to the gullies and ravines that add quiet climbing to routes most people outside the city assume are flat.

The race calendar here leans toward themed, community-spirited events where the vibe is welcoming and the finish-line shirt is essentially a given. Resolute Brewing and the trail corridors near Cherry Creek are where you will find runners before and after race day, and that low-key social thread runs through the events themselves.

How we calculate these stats: RunSesh calculates these figures from the most recent published results of past editions, sourced from RunSignup. We show aggregates only: field size, winning and median times, and the cutoff. We never publish individual finisher tables. Last updated Jul 27, 2026.
