Quad Rock 50 Mile sends runners on two back-to-back laps of a 25-mile course through Lory State Park and Horsetooth Mountain Park west of Fort Collins. The first loop runs clockwise; the second loop covers the same trails in reverse, making each half a unique experience. Expect 11,000 feet of climbing, 85% singletrack, exposed ridgelines with sweeping views east across the Great Plains to Nebraska and west to a towering Longs Peak, and a festive post-race gathering at Soldier Canyon.

Early May on Colorado's Front Range brings a wide range of conditions. Race day temperatures typically start in the low 40s°F before the 5:30am start and warm to the mid-60s°F by midday. Afternoon thunderstorms are possible, particularly on the exposed Horsetooth ridgeline. Lingering mud and snowpack at higher elevations are not uncommon in early spring. Runners should carry a light layer for the pre-dawn miles and be prepared for rapidly changing mountain weather.
