I have run this twice as it is less than an hour from home. It is a pretty course and I don't consider it terribly hilly. It is not flat, but the elevation gain is gradual. (According to my Strava, the largest gain in elevation is during mile 12 at 41 feet. Next are miles nine and thirteen at 26 feet. The rest of the miles were less than 20 feet or even negative.)
My biggest complaint is that, while running along the river is pretty, it also means a good portion of that part of the course is banked. It is an open course and, unfortunately, the flatter portions of the road always seem to be on the wrong side.
Now that Shenandoah Half the week before? That course is a beast.
Feel free to PM if you have any questions. Or I can send you some screenshots of the elevation changes per mile.
ETA: Obviously the banking of the road didn’t keep me from running it a second time. I just wouldn’t run it as a POT.
