The Bear Chase 50 Mile

2026

The Bear Chase 50 Mile takes place in early October at Bear Creek Lake Park in Lakewood, Colorado. This is a four-loop course of roughly 12.5 miles each, with about 870 feet of climbing per loop on mostly single-track dirt trail. The route stays within the park boundaries, moving through varied terrain that includes some technical sections and the notable Mt. Carbon climb on each loop. At 5,400-5,800 feet elevation, October temperatures are typically manageable, though conditions can vary. Runners will see a mix of prairie and foothills landscape, with the course following established park trails that wind around Bear Creek Lake and through the surrounding open space. The loop format means you'll pass through the start/finish area multiple times, creating opportunities for crew support and gear changes. This race works well for runners looking to step up to 50 miles without excessive technicality or extreme elevation gain. The repetitive loop format lets you dial in nutrition and pacing strategies, though some find the mental challenge of multiple laps more demanding than the physical course itself. Strong trail runners comfortable with moderate climbing and longer efforts will find this manageable, while those seeking highly technical terrain or significant vertical might want to look elsewhere.
