The Story of El Oso Loco
El Oso Loco (The Crazy Bear) Trail Race Series is a summer, mid-week race series meant to highlight the incredible trails of the Bear River Range in the Uinta-Wasatch-Cache National Forest, while bringing together the local trail running community. The series was developed in 2023 to showcase the trails we have here in Cache Valley's backyard and get more community members involved in the Adopt-a-Trail program in partnership between Cache Trails Alliance (CTA) and the local Forest Service district. All proceeds made through registration fees and t-shirt sales will help CTA grow staff, programming, and resources that will benefit our growing community of trail users.

Please fill out this form as soon as possible, or at least 24 hours in advance if you cannot make a race in the series. This will allow us to open your spot up to an individual race registrant.
