Hiked to the summit on July 22, alone and in celebration of my 60th birthday.This was a beautiful hike and although I did not prepare as most recommend, I am in excellent physical condition (I run on the treadmill 8 or so miles most days). Had a great time and although the hike was challenging, it was considerably easier than I expected. Left my home in southern Orange County, California, at 10:30 pm on July 21. Arrived at trail head at 3 am and started hiking. Took 5 and a half hours to reach the summit (passed more than 60 other hikers), spent 30 minutes on top, and took 4 and a half hours to get down. Kept expecting the altitude to really slow me down, but it was never a problem even though I had made no attempt to acclimate. Picked up something from Carls jr in Lone Pine and drove home, arriving at 6:30 pm. It was a tiring but thoroughly enjoyable 20 hours.
