Bristow Trail Run

Lace up your trail shoes for the Bristow Trail Run, an engaging event held on Sunday, March 1, 2026, at the scenic Elijah Bristow State Park in Dexter, Oregon. This race, part of the well-regarded Run Big Trail Series, offers a variety of distances to challenge every runner: a 50K, 25K, 10M (actually 10.4 miles), and 5M (5.2 miles). The course itself features a 5.2-mile loop entirely on single-track trails that wind adjacent to the picturesque Willamette River.

Runners can expect a uniquely flat trail experience, with elevation changes of less than 10 feet throughout the course, which for some, presents its own kind of challenge due to the constant running without the typical breaks of climbs and descents. The terrain is predominantly wooded and often wet and muddy, so proper trail footwear with good lugs is recommended. Depending on river levels, participants may encounter short stream crossings, typically 5-10 meters long and less than a foot deep. Typical race day conditions in early March bring highs around 52F and lows around 38F, with about a 25% chance of precipitation, creating that classic Pacific Northwest trail running atmosphere.

Throughout your chosen distance, you'll be well-supported with aid stations. There are two aid stations strategically placed on the 5.2-mile loop, ensuring runners pass them twice per loop, for a total of four opportunities on each circuit, plus an additional station at the start/finish line for those tackling multiple loops. These stations are stocked with water, Gatorade, GU Energy Gel & Electrolyte Brew Tablets, light snacks, and basic first aid. Runners are also welcome to drop their own preferred supplements at the aid stations before the event. The Bristow Trail Run is known for its organized execution, providing a welcoming environment for all participants.
