The Boulder Field Ultra, set for September 12, 2026, in the scenic Hickory Run State Park in Jim Thorpe, PA, promises an unforgettable challenge for trail runners and hikers alike. Offering distances of 100K, 50K, and an 18-Miler, this event is renowned for its unique and rugged Pennsylvania terrain. The course, largely composed of single-track hiking trails and wider multi-use paths, winds through the beautiful state park, providing stunning valley views and a dynamic running experience. Expect approximately 4000 feet of elevation gain per 50K loop, navigating a mix of rolling trails, rocky sections, and abundant roots.

What truly sets this race apart are its formidable features: the infamous Boulder Field crossing and the rugged Shades of Death Trail. The Boulder Field, a less-than-a-mile stretch of massive, jagged rocks, demands careful navigation rather than running, often described by past participants as a "tip-toeing" effort. Similarly, the one-mile Shades of Death Trail is a highly technical section featuring steep climbs, rock ledges, natural waterfalls, and challenging obstacles, pushing runners' limits amidst breathtaking scenery. Despite these demanding segments, the course is balanced with runnable sections and old jeep roads, making it a mid-level difficulty trail race.

Organized by Uberendurancesports, a group celebrated for its well-managed events over the past 15 years, the Boulder Field Ultra maintains a strong sense of community and excellent support. Aid stations are frequent and well-stocked with water, Gatorade, and various snacks, though carrying at least 16oz of fluid is highly recommended between stops. The start and finish are conveniently located at Sand Spring Lake within Hickory Run State Park, an area with options for camping and easy crew access. Typical race day conditions in September see comfortable highs around 75F and lows around 55F, with a 16% chance of precipitation, creating ideal conditions for a challenging yet rewarding adventure.
