This smallish marathon is staged on an out-and-back course that follows a section a rails-to-trails conversion north of Baltimore. The surface is primarily compacted dirt and gravel. The course is very flat, with a 1/2 percent grade climb on the way out and a corresponding 1/2 percent grade on the return (it's rated a 2+ on the 10 point marathon difficulty scale, 1 for the fastest courses, 10 for the most challenging). I can recommend this race for anyone wanting a flat course and/or for those who prefer softer running surfaces.
