This is such a beautiful route!
We parked at the Weaverton Rd. parking lot in order to park for free - and to check off the most-crowded of the three overlooks before the crowds woke up.
We started and finished at the base of the stairs that signify the start of the climb up to Weaverton Cliffs.
We hit the Weaverton overlook first, then Maryland Heights, then Loudoun Heights. We did make a minor mistake from the original FKT route submitted here - in that the original route follows the Appalachian Trail above Harper's Ferry only once; covering the same distance by road to close the loop... we took the Appalachian Trail both ways. This did not affect the total distance but it did add roughly 500 feet of extra elevation, and some time.
We stayed together the whole way, and saw very few people out all day. We carried all of our own nutrition and hydration - no refills needed for this distance or in the cold.
The weather was brutal, with cold temps and high winds - we used this as a fun long run, and it can definitely be run faster! I hope this route starts to get more action either as FKTs or just a great/scenic workout for locals!
