Some Initial thoughts on my first ascent of Mt Whitney, July 25, 2010.

Age: 61
Weight: 180
Height: 6'3"
Very Fit for my age.
Stayed overnight at trail camp on the 24th.
Acclimated by staying at Horseshoe Meadow one night and then another at the Portal Campground.
Starting pack weight at the Portal: 24.5lbs (food and water included)
Ending pack weight:(with Wag Bag -- don't ask) 22 lbs.

Section between Outpost Camp and Trail Camp has switchbacks which are worse with taller step ups and steeper grade than the 99 switch back from Trail Camp to Trail Crest. Except for the issue of altitude, if you can make these switchbacks then you can do the 99. And Don't Count Them! No one agrees on the number and it only makes you pay too much attention to how many there are. There are a lot. Just leave it at that.

Step ups on both sections average between 7-10 inches mostly but many are 10-15 or taller. Making the 10-15 inch ones shorter by carefully choosing your foot placement will help make the climb easier.

Having something to distract you from the relentless climb may be helpful. I listened to a Terry Prachett novel read by Stephen Briggs, hilarious and diverting.

99 switchbacks are surprisingly moderate in their grade.

For the lower section of the switchbacks there are many times when you have to cross running water from snow melt or walk in the trail running with water. (One could see this as an added source of supply if you wanted to skimp on your water carrying.)

Training really helps. Doing training which strengthens your stepping up and down muscles makes all the difference. I climbed the 3600 feet of net elevation to the top of Mt Wilson every Friday for several months with my pack at 25 lbs.

I found wearing my trail runners was effective in making this climb. You really, really don't need mountaineering boots or any heavy boot to make this climb. Most people I saw on the trail were wearing lighter footwear with many wearing trail runners.

3 liters of water with hydration tabs like Elixer (highly recommended) in the water is about all you need to do the actual climb and descent to and from Trail Camp. I had 3 liters and got back to Trail Camp with about 1 liter left.

I found that eating Snickers bars and carrying a couple of GU squeeze tubes really was all I needed for energy and nourishment.

Trekking poles are a must. But learn to use them effectively before doing Whitney.

Climb can be divided into 3 sections.
1.Switchbacks to Trail Crest. Moderate Grade. See above comments.
2.Trail Crest contouring to Mt Whitney behind the Needles. Very rocky! Unstable footing in many places. A lot of rock hopping.
3.Whitney serpentine trail to the Summit. Gentle grade up the slope of the back of the mountain following a snake like path.

I'll post my more detailed Trail Report when I have had a chance to copy my trail journal notes and clean them up.
