25k (16 miles) or 50k all trail, and a rockin' after-party! One long trail run on varying terrain, mostly forest shaded. Everything from rock scrambling uphills to single track downhills, to mountain bike havens, numerous stream crossings and as few fireroads as possible in order to get you back on lovable dirt enlightenment. ~2000 ft of upward elevation on the 25k and 4000' for the 50k. The trails are very technical and challenging. A great course to hike, run, or both. Its really an adventure and a beautiful park. You won't know you are 8 miles outside Baltimore. 3 Aid Stations with plenty of water and some food. Aid for the 25k will be every 4 miles, so at 4, 8, and 12. Course markings and detailed maps will be included. The after party will include 2-3 craft-brew kegs, pulled pork, BBQ, river swimming, cornhole and horseshoes.
