This is one of my favorite rides. From our chalet to Cades Cove and riding the loop is a 75 mile trip. The elevation gain is only about 5500' as a lot of the ride is along Little River Road. There is a decent climb to Fighting Creek Gap and another to the cove. The loop around the cove is flat to rolling with a few short but steep climbs. There wasn't much traffic but the spikes in power are from passing cars and the short climbs. Average power over the 4:40 was just under 200 watts so Endurance pace all the way.
