Course
Run entirely inside Portland's Forest Park. The 50K takes in the Wildwood Trail and quieter paths deeper in the park; the half marathon uses a shorter loop of the same network. Both are singletrack and park-path courses with sustained climbing.

About
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.
