Crown Stub 100

Crown Stub 100 is a 100 mile ultramarathon held at Stub Stewart State Park on April 4th 2026. The course records over 7,000 feet of elevation gain and combines multiple surface types: asphalt on the Banks Vernonia State Trail, hard packed gravel on the Crown Zellerbach Trail, and about ten percent single track dirt within the park.

The route is a double out-and-back from the park. Runners proceed north on the Banks Vernonia Trail into Vernonia, circle Vernonia Lake, then follow the Crown Z Trail roughly twenty miles east before turning back near the outskirts of Scappoose. After returning past the park crossing at Stewarts Gate the course continues south on the Banks Vernonia Trail to Banks, then back to Stewarts Gate and onto the Boomscooter Trail toward the Hill Top Day Use area. Near the finish runners complete one final lap of the 6.5 mile Stub Stewart Trail Challenge.

There are 13 aid stations along the course. Four aid stations are full service, including Stewarts Gate and Vernonia, offering a wide range of food options; other stations provide typical trail foods. Skratch Labs supplies hydration and chews and a gel will be available. Runners may use two drop bags accessible at Stewarts Gate and Vernonia on multiple occasions. Crew access points are provided, but participants may be disqualified for being inside a vehicle at crew points. Pacers are allowed beginning at Pisgah Aid Station 5 at approximately mile 40 and may not carry a runner's gear.

The 100 mile division has a 32 hour completion limit. The Ultra Relay division traverses the full course with relay partners required to swap at each exchange and a 30 hour completion limit. A 10 percent registration tax will be withheld and distributed to the event winners titled King and Queen of the Land of Stub. Visit the organization's website for the most recent information.
