Backcountry Wilderness Half Marathon Highlands Ranch, CO   Nov 7, 2026

The Backcountry Wilderness Half Marathon delivers a true Colorado trail running experience—challenging, scenic, and unforgettable. The single-loop, 13.1-mile course is 100% dirt, gravel, and singletrack, taking runners through the stunning Front Range landscape with opportunities to spot wildlife and soak in expansive mountain views.

November trail running can mean mud, snow, or ice—and we welcome it all. The race will proceed in rain, shine, sleet, or snow unless excessive moisture makes the trails unsafe or inaccessible, in which case a postponement may occur.

Whether you’re chasing a personal best or taking on the trails for the first time, this race delivers a rewarding test of endurance and Colorado beauty.
