Forest Park is a gem in the city and a chance to race on the trails here is not to be missed, by locals who run here regularly and for visitors to town looking to experience what we Portlanders get to call our backyard. Forest Park is a 5200-acre park in the middle of Portland with over 80 miles of trails. You’re never far from the city, but can figuratively get lost in the woods of the Tualatin Mountains.
The only 50K held in Portland, the Stumptown Trail Runs route will include everyone’s favorite – the iconic Wildwood Trail, a National Recreation Trail – but also some lesser-known paths deeper in the park. The 50K has 4,000′ of elevation gain.
The Stumptown Trail Runs half marathon is fun but also a challenging trail race that serves up all the shades of green and a good amount of hills with 1,800′ of gain and loss.
These are running events; not walking races.
Both races benefit the Forest Park Conservancy again this year.

After you finish Stumptown, we feed and rehydrate you while you hang out with friends and family.
Every finisher earns a Stumptown pint glass. The top 3 male, female, and non-binary finishers receive prizes from our sponsors. We also have awards for 1st-3rd place age group (in 10-year age categories). There are plenty of great raffle prizes too.
The race start is a quarter mile up Leif Erikson from the gate at the top of Thurman St. Map.
Parking is on neighborhood streets. Carpooling, taking public transit, or ride share is highly recommended as the parking can get tight and we need to be respectful of the local residents. Do not block driveways.
Given that the park borders private property, there is NO PARKING for spectators at ANY of the aid stations.
If you are interested in carpooling, you can post here to find or give a ride. This is a Google spreadsheet that is viewable to anyone with the link, so only post what you want public. Carpooling can earn you $5 cash and a $5 drink gift card from Nossa Familia Coffee – read about this program here.
We love volunteers and our racers do too! To make this race a success we need people to help at bib pickups, race start and finish, aid stations, and on the trail. You can sign up for the assignment you’d like on Ultrasignup. Click on the green Volunteer button with the heart.
We do have a few rules that apply to all Go Beyond Racing races. Be sure you are familiar with them.
