The Bear Chase Half Marathon sends runners on a single loop of the 13.1-mile Orange Course through Bear Creek Lake Park — the same loop the ultra runners complete multiple times on Saturday. Three named climbs, sweeping Front Range views, and 99% smooth singletrack make it a memorable introduction to trail running for road runners ready for their first taste of dirt.

Course features 'Mount Carbon,' 'Red Rocks View,' and a mystery third climb — ask a Bear Chase veteran for its name

Same 13.1-mile Orange Circuit the 100K runners repeat five times — experience it once as a standalone trail half

Peaceful morning start at Bear Creek Lake Park with panoramic views of Denver's Front Range foothills
