HAT Run 50K

Hello HAT runners, volunteers, and fans, 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!)   REGISTER HERE There will be a 350 runner cap on the 2025 race, register early.The Steppingstone Farm Museum serves as our race day headquarters as well as the start/finish line.
