Rosaryville Half Marathon, 10K, 5K Trail Run

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 in nature, this race course is perfect for an early season trail running race. The race course 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. The 5K course consists of part of the perimeter trail and some equestrian trails. Our charity partner for this event is City Kids. If you are able, please consider making a donation to this amazing organization during registration.
