Stumptown Trail Runs
Portland, United States • 23-25 May 2026
Stumptown Trail Runs : Forest Park, Portland
Stumptown Trail Runs are trail running events held in Forest Park in Portland over the Memorial Day weekend. The event offers the following distances:
- 50K Portland's only 50K trail race, includes the Wildwood Trail, almost 4,000' of elevation gain.
- Half Marathon Trail race with hills and 1,800' of cumulative gain and loss.
The 50K route includes the Wildwood Trail, a National Recreation Trail, and additional lesser-known paths deeper in the park. Forest Park covers more than 5,100 acres and contains many miles of recreational trails in the Tualatin Mountains near the city.
These are running events, not walking races. Both races benefit the Forest Park Conservancy. Post-race provisions for racers include just-baked pizza and a finisher pint glass. Awards go to the top three male, female, and non-binary finishers, with additional 1st–3rd place age group awards in ten-year categories and raffle prizes.
Registration fees vary by date and include optional merchandise; there are no transfers and no refunds. A cancellation more than 30 days before the race receives a 50% credit toward a future Go Beyond Racing event; cancellations 30 days or less before the race receive no credit. Parking is on neighborhood streets and there is no parking at aid stations. Volunteer roles include bib pickup, aid stations, and on-trail support.
