From the official website:

Hello HAT runners, volunteers, and fans,

March 25th, 2023 will mark the 33rd 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!)

Registration will open November 25, 2022 on

ultrasignup.com

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 on ultrasignup.com

We’ll be ready for you on March 25th, 2023. Don’t miss this great ultra-run experience!
