About the Labor Day Trail Challenge 50-Mile • 50K • Marathon • Half Marathon & Ruck • 8-Hour Run/Walk • 8-Hour Relay
McKinney Roughs Nature Park sits along the Colorado River and holds a genuinely varied landscape. The trails move through box canyons, pine forest, wildflower meadows, and river bluffs, so the terrain shifts beneath you throughout the run. Expect technical single-track with real elevation, not a groomed path, and overlooks where the Colorado opens up below the ridgeline.
The park draws from several distinct ecosystems packed into one preserve, which means the surroundings change noticeably as you move through. Several distance options make it accessible to trail newcomers and ultra runners alike. Aid stations along the course are stocked with water, electrolytes, and snacks.

The Labor Day Trail Challenge 50-Mile • 50K • Marathon • Half Marathon & Ruck • 8-Hour Run/Walk • 8-Hour Relay has been held every year since at least 2026. That is as far back as RunSignup's records for this race go, so it may well be older.
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 Oct 25, 2026.
