Mt Diablo hike

Holy cow - What a hike! On Saturday I joined 11 other folks to hike up to the summit of Mt. Diablo in the East Bay and this 12 mile hike kicked my butt. To be kind I will say there was about 3,300 foot elevation to get to the top from the spot where we parked the vehicles (and the corresponding elevation drop) so the fact that I can't walk well is probably reasonable. Some parts were probably 45% in grade and these were the ones that hurt on the way back down. Yikes. If I can hike this trail, even twice a month, then I should be able to hike the PCT… I've never seen a trail close to this kind of steepness before, where I wasn't wearing a helmet and attached to a harness.
