Does anybody here ever travel on River Road? I don't think so, but it is worth a shot.
I want to do an unsupported century looping into Carmel Valley, but I cannot think of anywhere to get water along the way. Even if I went out of my way to go into Greenfield, it would still be 40 miles before I can get to Carmel Valley Village and that is with a long climb. I can go once again out of my way and go to the Cachagua General Store, but that requires some more climbing. I love climbing, but that would be overall too much for a solo century.
It is hard to carve out a 100 mile bike ride since there is the ocean on one side and mountains on the other.
