About
Portland Trail Series - Summer runs in Portland, Oregon, from April 2, 2027, as a set of evening trail races in Forest Park, each covering roughly four to seven miles and starting at 6:15 PM. The trails wind through shaded woodland inside one of the city's large forested parks.
A series format is a different proposition from a one-off race: instead of a single target you get repeated efforts on the same ground, which is one of the best ways to learn how to run trails. You find out where you can push, where the footing punishes carelessness, and how your pace compares from week to week on a course you know. Distances in this range suit road runners crossing over to dirt, since the length is manageable while the surface is not. Evening starts mean eating properly during the day and doing a longer warm-up than you would in the morning.
