Embark on an unforgettable trail adventure at the Boulder Field 100 on September 12, 2026, nestled within the breathtaking Hickory Run State Park in Jim Thorpe, PA. Offering challenging distances of 100K, 50K, and an 18-Miler, this race is renowned for its unique terrain and stunning Pocono Mountains scenery. Runners will tackle a figure-8 shaped 50K loop, with 100K participants completing two loops. The course features approximately 4000 feet of elevation gain per 50K loop, comprised of 90% single-track and wider multi-use trails, with only about a mile of gravel road. Be prepared for the race's signature sections: the aptly named "Shades of Death Trail," a rugged and technical mile-long stretch, and a less-than-a-mile crossing of the ancient Boulder Field itself—a truly unique and challenging natural phenomenon. Despite these formidable features, the Boulder Field 100 is considered a mid-level difficulty course, balancing technical sections with more runnable segments, making it rewarding for both seasoned ultrarunners and adventurous first-timers.

Organized by Uberendurancesports, a group with a strong reputation for well-managed trail events, the Boulder Field 100 was specifically designed to offer a more demanding experience than their typical beginner-friendly races. Aid stations are strategically placed approximately every 5 to 7 miles, offering water, Gatorade, and a variety of snacks and carbs, all staffed by experienced ultra runners dedicated to supporting your journey. Typical race day conditions in mid-September see highs around 75°F and lows around 55°F, with a modest 16% chance of precipitation. The race fosters a vibrant community atmosphere, enhanced by free tent camping available for runners and their families, ensuring a full weekend of camaraderie and trail spirit.

Whether you're aiming for the full 100K challenge, the demanding 50K, or the spirited 18-Miler, this event promises a memorable test of endurance against a backdrop of varied and beautiful landscapes, including ridge views and serene streams. The generous time limits for the 50K and 18-Miler also make them welcoming options for hikers looking for an epic adventure. Come and discover why runners rave about the well-marked course, exceptional aid, and the sheer exhilaration of conquering the Boulder Field.
