What the course asks

Time limit 12 hours 9:00 min/km average. Comfortable. Room to walk the climbs and stop at aid. Climbing is unpublished, so this pace is a ceiling on the effort, not a measure of it. Among the tightest 50 mi cut-offs we track. Measured against 471 races of the same distance. Cut-off calculator →

Field size ~133 Mid-sized. Company early, well spread out by halfway.

DUV results for the 2026 edition (50mi) — finishers only. Starters are not published, so the field was at least this big and no finish rate can be given.

Overview

The Dirty German Endurance Fest 50 Mile, organised by Uberendurancesports, takes place in Philadelphia, PA in May. With 10 past editions since 2016, the race has a larger field than 81% of 50-mile races. The latest edition in 2026 saw 133 finishers.

The 12-hour time limit for this 80-kilometer trail race through Pennypack Park translates to a 9-minute per kilometer cutoff pace. This cutoff is tighter than 85% of 50-mile races, leaving less margin for error or a slower pace. The park's trails stretch along Pennypack creek for about 7 and a half miles.
