The first bit of Calaveras Rd just after you turn right from Piedmont Rd. is fairly steep, about 10%. It doesn't last long though (btw, this is not the Calaveras Wall if anyone is wondering, that's farther up, about a mile past Ed Levin park). After you get over that hump, then the road levels off to a more gradual climb to Ed Levin Park.

The descent back down is really fun though!
