Join EX2 on Saturday March 28th for our annual Rosaryville Trail Half Marathon, 10K, and 5K!
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.
There are 9 aid stations on the half marathon+ course, 4 aid stations on the 10K+ course, and 2 aid stations on the 5K+ course. All aid stations have cups, water, and gatorade. One aid station on the half marathon course also has snacks (~ 8.8).
