Race Information

Conveniently located right off the Capital Beltway, Rosaryville State Park in Upper Marlboro, MD offers fun and challenging terrain, that is also beginner-friendly. Not overly technical, this racecourse is perfect for an early-season trail running race. The racecourse at Rosaryville is beautiful and fun and winds through mixed hardwood forests and fields. The trails are twisty, relatively smooth, relatively flat, and fast. The half marathon course includes the 9-mile perimeter trail, the 2-mile interior trail, and wide-open horse trails. The 10K course includes 5 miles of the perimeter trail and just over one mile of wide-open horse trails.

Run Pick of the Month - Ragnar Trail Appalachians

 8 Teammates. 120 Miles. 3 Loops. Camping. August 9 - 10, 2024.

In this multi-day event, each team will collectively run 120-ish miles. You’ll run day, night, and day again, sleeping in a temporary tent city known as the Ragnar Village.

When you’re not racking up miles for your team or attempting to catch some ZZZs in your tent, you’ll be hanging out in the Ragnar Village, roasting s’mores, winning partner prizes and partying with other runners.

At the Appalachians event teammates will take turns running on 3 tree lined trails full of dense Appalachian forest. Expect rolling hills with serious elevation, and giant ferns reminiscent of Jurassic Park...... minus the dinosaurs!
