Bristow Loop Race

The Bristow 24/12/6 Hour Run is a timed loop race lets runners challenge themselves to see just how many miles they can run in a set time limit. The course is a 1.05-mile, almost all trail, loop through Elijah Bristow State Park, just 30 minutes east of Eugene, Oregon. There is a 24-hour, 12-Hour, and a 6-Hour option – and new for 2025 – a 12-Hour Night Relay. An amazing aid station is available every loop and/or runners can set up their own space to feed and fuel themselves or have a crew there to support them along the way.
