Tyler Arboretum 10k Trail Run

Prepare for an exhilarating journey through nature at the Tyler Arboretum 10K Trail Run on April 4, 2026, in Media, PA. This premier 10K event invites runners to traverse the historic and breathtaking 650-acre Tyler Arboretum, offering a rare opportunity to race within its stunning grounds. The course is a dynamic blend of wide, well-maintained paths, frequent elevation changes (including nearly 1,000 feet of elevation gain), and four engaging shallow creek crossings, ensuring both a challenging experience for seasoned trail runners and an enjoyable adventure for novices. Starting with a flat half-mile sprint from behind the Tyler barn, runners will quickly immerse themselves in the arboretum's beautiful gardens, fields, and forests.

As a cherished spring tradition, the Tyler Arboretum 10K Trail Run holds a reputation as a "must-do race in Delaware County" and stands as the only sanctioned race hosted in this picturesque setting. This event, presented by the Delaware County Road Runners Club, is part of the USATF Mid-Atlantic Grand Prix Off-Road Running Series, drawing a supportive community known for its camaraderie and exceptional volunteer support. Typical race day conditions in early April feature comfortable highs around 61F and lows near 41F, with only a 13% chance of precipitation, providing ideal weather for a memorable trail experience.

Beyond the competitive spirit, this race is celebrated for its unique atmosphere and generous swag. Runners often praise the clearly marked course and the lively experience of splashing through the Dismal Run Creek crossings. A portion of each registration directly supports the arboretum's year-round programs, allowing participants to contribute to a worthy cause while enjoying post-race camaraderie with hot drinks and snacks. Prizes, including the special "King and Queen of the Hills" awards for top Delco RRC members, add to the excitement of this beloved and enduring trail race.
