Dirty German Endurance Fest

The Dirty German Endurance Fest is an urban ultramarathon held within Philadelphia's Pennypack Park, a scenic area featuring trails along Pennypack Creek with diverse surfaces including soft dirt, sandy spots, single track, gravel, and some paved bike trail. The event offers 25K, 50K, and 50-mile distances, with courses designed to be runnable and not overly technical, featuring short climbs and shaded paths. Over 600 runners participate annually in this well-marked race.

Finishers receive a zippered running jacket, commemorative bib, and medal, with unique German-themed awards for top finishers. The event includes a festive post-race party with live music and gourmet food. Visit the organization's website for the most recent information.
