The Story of the O-Sho Trail Series

The O-Sho Trail Series is all about bringing beginner and novice trail users together to build community around trail running and celebrate the incredible access we have along the Bonneville Shoreline Trail. This fun(d) run raises money that goes right back into maintaining and improving the Bonneville Shoreline Trail. We encourage participants to bring food and beverages to enjoy after their run and stick around to cheer on the rest of the runners out on the trail!

Race Schedule
