The Portland Trail Series, produced by Go Beyond Racing, is renowned for its highly organized events and supportive atmosphere. Participants can expect well-stocked aid stations and friendly volunteers dedicated to ensuring a positive and safe race experience. While each race features a unique, challenging route, maps are typically posted on the Monday prior to the event, allowing runners to preview the course. For those who embrace an element of surprise, some series races may even feature a "Mystery Route," keeping the specific trails under wraps until race day, though the course will always be clearly marked.

Typical race day conditions in late May bring comfortable highs around 71°F and lows around 51°F, with only a 12% chance of precipitation, creating ideal weather for tackling the scenic trails. This series is more than just a race; it's a community event that culminates in an awards party at the Lucky Lab Brew Pub after the final race, celebrating series winners and offering fantastic raffle prizes. Whether you're aiming for a personal best or simply seeking a vibrant trail running experience, the Portland Trail Series - Spring offers an engaging journey through Portland's natural beauty.
