This race offers a perfect opportunity for runners  to enter the exciting 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 occationally sandy spots along the creek, a lot  of smooth single track as well as some wider flat gravel trail. Every loop includes about 1 mile 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.

Winner  overall male and female
will receive an authentic German cuckoo clock.

Top 3 in age groups: 29 & under, 30-39, 40-49, 50-59 and winner 60+ 

These unique awards come from the Black Forest of  Germany.  They are german weather houses. They can predict future weather  pretty much as reliable as "Glen Hurrican Schwarz" . Here is how they work:              There is a gut string inside which reacts to all changes in air humidity. Depending on wether the air is dry or humid, the gut string changes it's position and twists more or less, so that the female turns outside when it is dry (predicting nice weather) and the male, when it is humid. We will go 3 deep for 18-29, 30-39, 40-49, 50-59 and winner  60+ .

St Pauli Girls

Along Pennypack Creek within the limits of Pennypack park. Course is basically a figure 8 consisting of mostly single track trail and a short 1 mile paved bike path section. One loop is 25K. 50 K runners will run it twice, 50 mile runners will run the main loop 3 times and an extra 1 mile dog leg section during each loop (well marked). This is a wonderful park setting, with gorgeous views of the creek, wildlife and nature within the city limits of Philadelphia
