Dirty German Endurance Fest

The Dirty German Endurance Fest 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 race offers a perfect opportunity for runners to enter the exiting world of trail (ultra)running . 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. The course features different surfaces. Some soft and occasionally sandy spots along the creek, a lot of smooth single track as well as some wider flat gravel trail. Every loop includes about 1.5 miles of paved bike trail. There is some elevation, but the climbs are short.

This course is very runnable and easy by trail running standards, which as experienced runners will know, can make it even more challenging, because it will not give you many opportunities where you can/should hike.
