Race #2 is May 20th. The Portland Trail Series is a set of five, low-key, evening races in Forest Park. Each race in the Series is a different course, all between 4 and 7 miles. The races are great for those new to trail running and Forest Park, and also a great speed workout for those experience trail runners. Race the Series and earn points toward winning podium and age group awards. We have an Awards Party immediately following the final race in the Series, at the NW Lucky Labrador Brewpub.
