The trails of Forest Park are a real treasure for runners and an opportunity to run a race on them shouldn’t be missed. The only 50K held in Portland, the route will include everyone’s favorite – Wildwood Trail – but also some lesser traveled and less well-known paths, with approximately 4,000′ of elevation gain.
The Trail Factor half marathon is a fun, challenging and well-supported race that includes beautiful trails and lots of friends and family.
Both races support the Forest Park Conservancy again this year.

There is a 1:30 p.m. 50K cutoff at the aid station at mile 21.4. If you are not able to make this cutoff, you will be asked to return to the start with aid station volunteers.
We’ll treat all racers to a post-race food and drink. It is a fun time to hang out with friends and family.
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. Please be respectful of private property and especially avoid blocking driveways.
Given that the park borders private property, there is no parking for spectators at any of the aid stations.
There are three hotels within a mile of the start/finish:
We love volunteers and our racers do to! 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.
Be sure to visit our Facebook page. There you’ll find updates and information.
