The first poster, Gary, has hooked up with an experienced hiker who has hiked the JMT before. I was planning on hiking it solo (if I couldn't find a partner) over a 3-week period but am getting rumblings at work about being gone for 3 weeks at one time even though I've gotten official permission to be gone. Now I'm reconsidering my options: 2 weeks and do half of it or see if there's a way to do it all in 2 weeks plus a day or two.
I saw your other post about hiking it solo. I've never hiked solo before but feel confident that it can be done safely on the JMT by experienced backpackers. I've read some of the journals of other first-time soloists and figured if they could do it, so could I.
