About the Philadelphia Trail Marathon

Wissahickon Valley park is the crown jewel of the Philadelphia park system. It is over 2000 acres in size and features more than 50 miles of trails. The park combines natural beauty and history, with many historic buildings and bridges located within the park. Philadelphia trail runners have embraced the park for many years for their training runs, due to its natural beauty and extensive trail network, but there hasn't been a long distance trail race in recent memory. Let's celebrate Philadelphia trails by running the Philadelphia Trail (Half)Marathon at the Wissahickon Valley Park. Over 600 runners have registered for the race in the past 2 years,and we are expecting a large field for the return to Wissahickon Valley. We are looking forward seeing you at the starting line in April. Source
