About
The Fifth Street Rock Monster takes place in Longswamp Township, Pennsylvania, in the first half of April, and is a trail event with four distances: a marathon (26.2 miles), a half marathon (13.1 miles), a 10K (6.2 miles) and a 5K (3.1 miles). All four start together at 9:00 AM. Pennsylvania trails often mean roots, rocks and mud in spring, so trail shoes with good grip and some practice on uneven ground will serve runners well, particularly in the two longer races. The mix of distances makes it possible to choose anything from a short introduction to trail running to a full day on the dirt.
