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!)

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. 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!

One last thing... speaking of volunteers. This race doesn't happen without the gracious donation of time from our many volunteers. When you come and experience HAT, you'll walk away feeling it was something special - that's not (only) the runner's high, it's because of our volunteers.

Check out our Runner's page for all the fine print (fees, policies, course map, etc).

Registration opens Black Friday, November 28 on ultrasignup.com

We'll be ready for you on March 21st, 2026. Don't miss this great ultra-run experience!
