Planning to drive down to Derwood and watch the races Saturday. Seems there is already a course in the park which local runners compete on, but is the nationals course going to be 2k loops like they usually have? It's more spectator friendly, but may cut down on the difficulty. There has been talk of how tough the course will be Saturday in MD (without the snow, slush, mud, etc) mixed in. Regardless, I just want to be able to see as much of each race as possible.
