36th Annual Hinte Anderson Trail Run 50K (HAT 50K)

A hilly circular running route, approximately 30.7 miles long.

March 21st, 2026 will mark the 36th running of this iconic spring ultra-marathon on the trails of Susquehanna State Park, in Havre de Grace, MD. The 50-kilometer course traverses single-track trails, intermixed with open fields, dirt roads, and as few steps as we can manage on black-top. Our course covers nearly every inch of the park over two identical loops with nearly 4,300 feet of climbing. Be ready for 4 stream crossings - (read: your feet will get wet!)

The Steppingstone Farm Museum serves as our race day headquarters as well as the start/finish line. By day’s end, the historic grounds will be filled with spectators, volunteers, and, of course, your RD’s welcoming you to the finish with a handshake and the best swag there is to offer. Check out the runner’s corner for course maps and more details.

Along the way, you’ll experience our world-renowned aid stations filled with everything you need to keep you hydrated, energized and inspired. If you aren’t running, volunteers and spectators are always welcome!
