The B&A Trail is 13.3-mile paved mutli-use path stretching from Glen Burnie to Annapolis. It’s one of the the best spots in the area for a long off-road run. The Baltimore trailhead is at Saw Mill Creek Park, near Baltimore-Washington International Airport. The Annapolis trailhead is off Boulters Way, just north of Highway 50. There are half-mile markers along the way. Choose a section or make it a marathon(!). Key distances and landmarks along the way, headed south:
3.3 miles: Pasadena
5.5 miles: East-West Blvd., Millersville
6 miles: B&A Trail Park HQ
8.6 miles: Severna Park (Earleigh Heights Ranger Station)
