Bristow 24/12 Run

Go Beyond Racing's Bristow 24/12/6 Run is a timed loop trail ultramarathon at Elijah Bristow State Park, about 30 minutes east of Eugene, Oregon. Runners complete as many 1.05-mile dirt-loop laps as possible in 24, 12, or 6 hours, with a 12-hour Night Relay added in 2025. The pancake-flat course gains about 16 feet per loop and is mostly dirt with a short pavement stretch near the aid/finish area.

An aid station greets every lap; camping, meals, and crew-friendly options are available. Finisher pint glasses, top awards, and 100-mile buckles help celebrate endurance and community. Visit the organization's website for the most recent information.
