About the Yellowstone Park Trail Races
The courses all start and finish at the Rendezvous Ski Trails, which means you are running on groomed ski terrain through the forest west of Yellowstone. Several distance options are available, from a short loop up through a full fifty-kilometer effort. Elevation gain builds meaningfully as the distances grow, so even the shorter courses have some real climbing in them.
Check-in opens at the Rendezvous Ski Trails on race morning, giving you time to get your bib before a pre-race meeting where the race director walks through course markings. The Forest Service recommends carrying bear spray on the course, and the organizers note this as well, so factor that into what you pack.

The Yellowstone Park Trail Races has been held every year since at least 2025. 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.
