A group of 6 of us did a 3 day tour from Harrisonburg, VA up through the mountains to the north and returning to Harrisonburg. The route was 130 miles with 11,000 feet of climbing and about 50 or 60 miles of the route were on gravel. Not sure if the correct term is bike packing or bike touring but who cares, we had fun. Four of the six had never toured before so this was a learning experience for them.
