About This Event

The 3 Bears Trail Races offer a nostalgic journey back to the original Bear 100 course that challenged runners from 1999 to 2007. This intimate gathering in Utah's Bear River Mountains brings together the Papa Bear 100-mile, Mama Bear 50-mile, and Baby Bear 50K distances on a demanding high-altitude course. The event has been inconsistently scheduled in recent years, with organizers noting it was not planned for 2023 and suggesting runners check back in 2024. Starting from Deer Cliff Inn, the races follow complex loop patterns that showcase the technical terrain and elevation changes that made the original Bear course legendary among ultrarunners. The Papa Bear 100-mile begins on Friday morning, while the shorter distances start on Saturday, creating a multi-day festival atmosphere for the small but dedicated field of participants.
