Yeah, if you are doing the metric route, train your butt for miles and do not worry about the hills. There are only a few hills and nothing big. I would have said the route was more like 1,100 ft of climbing.

Even at 1671 ft, that's only 26 ft/mile.

Diablo from Arbolado Park and back is 144 ft/mile.

Rest easy and train for distance.
