This race takes place within the city limits of Philadelphia, and therefore, qualifies as an urban ultramarathon, but you will not find things like traffic, noise, bad air quality & concrete buildings here. This race course is located within Pennypack Park, a hidden gem within Philadelphia's Fairmont park system. The park stretches along Pennypack creek for about 7 1/2 miles and is home to many trails, huge old trees, birds & other wildlife. This is a good course to run your first ultra or a PR if the weather cooperates. We accomplish this by providing a course that is well marked & not too technical.
