The Stub Stewart Trail Challenge is not your average race—it’s a choose-your-own-adventure through one of Oregon’s most versatile state parks. With multiple distance options decided on race day, you get to test your grit against the trail and decide how far you’ll go once you’re out there. Whether you’re feeling strong enough to tackle the full marathon or want to stop after a half, your finish is celebrated and your results will reflect the challenge you conquered.

Expect a mix of pavement, dirt road, forest singletrack, and short steep climbs that keep your legs and your mind engaged the entire way. The coveted Golden Trucker awards await the top finishers, but every runner gets the satisfaction of pushing through mud, hills, and ever-changing terrain to earn their Bivouac Racing mug, post-race food, and beer. With community vibes, diverse trails, and an anything-can-happen format, this is a race you’ll be talking about long after the finish line.
