I decided to challenge myself and do San Jacinto as the Cactus to Clouds starting from the trailhead behind the Palm Springs Art Museum. This makes it 22 miles with a little over 10000 ft of elevation. I started at 3am and got to the tram station a little before 5pm. Minus the effects of higher elevation, this was definitely more difficult than Whitney. If you have been training and especially if you have done Whitney this is definitely doable. It is as much mental as it is physical to just keep pushing through. The views, the change in scenery going from desert to forest and the sense of accomplishment make it all worth while.
