Lace up your trail shoes for the Stub Stewart Trail Challenge on April 5, 2026, a "choose your own adventure" race set amidst the stunning landscapes of L.L. Stub Stewart State Park in Buxton, Oregon. Offering distances of 26.2M, 19.5M, 13.1M, and 6.5M, this event stands out for its unique format: all distances are based on a challenging yet rewarding 6.5-mile loop, allowing you to decide how many loops you'll tackle on race day itself. Whether you're aiming for a single loop or pushing for a full marathon, the flexibility ensures a truly personal challenge.

The course itself is a runner's delight, combining pavement, "unapproved road," and true forest singletrack, making for a diverse and engaging experience. Expect a mix of rolling hills and challenging climbs, including the ascent to the park's highest point at 1,500 feet, which rewards runners with magnificent panoramic views of the Coast Range. Reviewers consistently praise the well-marked trails and beautiful scenery, though runners should be prepared for varied terrain, including potential mud given the season. Typical race day conditions in early April feature highs around 55F and lows around 35F, with a 20% chance of precipitation.

Starting and finishing at the Hilltop Day-Use Area, the Stub Stewart Trail Challenge, organized by Bivouac Racing, is known for its strong community atmosphere and efficient operations. Aid stations are available on the course, though participants should bring their own drinking vessels as it is a cupless race. Beyond the challenge, all finishers are celebrated with a Bivouac Racing mug, post-race food, and beer, while top male and female finishers earn the coveted Golden Truckers award. Don't forget the $5 park permit required for parking at this scenic Oregon gem.
