Our course through the beautiful Lehigh Parkway is relatively flat and fast by ultrarunning standards, with a soft and very runnable crushed gravel surface for the majority of every 10K loop. A generous 10-hour time limit and a loop course with access to aid stations every few miles make this race perfect for a first 50K ─ or for setting a new PR at this distance. And if you’re not up for the whole challenge but can run at least 10K, then grab some runner friends for a relay team and cheer each other on throughout the day! Runners will pass under 182-year-old Bogert’s Bridge, one of the oldest covered bridges in the U.S. and the inspiration for our race logo.
