I just got back from the Sierra on Monday -- we probably just missed each other on the trail. My wife and I did the 54 miles from North Lake (Piute Pass) to South Lake (Bishop Pass). She'll only do around 11 miles/day, so I'm still wanting to get out again this summer to do some faster-paced hiking.
Last year about this time I did something a little different that I'd like to try again. I set up base camp at Merced Lake in Yosemite and did three trail runs on successive days -- there are three great loops from Merced Lake, 17 - 20 miles each. I mostly walked the uphills, taking 5+ hours to complete each loop. I have no idea if you've done any trail running, but just thought I'd throw this out as a possibility.
If you're interested in another backpacking trip, or some trail running, you can email me (clark @ xidak.com) -- I'm in the Palo Alto area. Anyone else? -- I don't really like running alone in the Sierra.
