Dirty German Endurance Fest

The Dirty German Endurance Fest is an urban ultramarathon held within Philadelphia's Pennypack Park, a scenic natural area featuring trails, wildlife, and Pennypack Creek. The event offers 25K, 50K, and 50-mile distances on a well-marked, runnable course with varied surfaces including single track, gravel, sandy creek spots, and some paved bike trail. The course features gentle elevation and a figure-8 loop design.

Over 600 runners participate annually in a friendly atmosphere. Finishers receive commemorative gear, and winners earn unique German cuckoo clocks and weather houses. A festive post-race party with live music and gourmet food completes the experience. Visit the organization's website for the most recent information.
