Boulder Field 100
The Boulder Field 100 is a challenging trail running event held at Hickory Run State Park in Jim Thorpe, Pennsylvania. It offers three distances: 100K, 50K, and an 18-mile run/hike. The course features a figure-8 shaped 50K loop, with 100K participants running the loop twice.
Runners encounter a mix of single-track and multi-use trails, including a rugged one-mile section called the Shades of Death Trail and a boulder field crossing, adding to the race's mid-level difficulty. Elevation gain is about 4,000 feet per 50K loop. Aid stations are well-stocked, and the event is known for being well-organized and beginner-friendly despite its challenges.
