Redwood (Spring) Trail Run 2027

The Redwood (Spring) Trail Run is a spring trail-running event held at Chabot Space & Science Center in Oakland, with races taking place within Redwood Regional Park. Participants can select from a short sprint or 5-mile run up to a half marathon, 30K, marathon, and 50K, accommodating children, novice trail runners, and those seeking a long run on trails. The course follows the park’s East Ridge and West Ridge trails, descending into sections of tall redwoods via the Stream and Bridle trails. The children's 50-yard dash is complimentary for ages six and under, youth 5-mile divisions offer reduced entry fees, and the primary adult distances commence in the morning. Distances are measured using a Rolatape surveyor’s wheel, a detail important for trail courses where GPS accuracy can be affected by tree cover and terrain.
