that's funny. i was already planning on doing the TRT in 5 days this summer. i did it in 2003 at a pretty mellow pace in 10 days. i'm also going with a golite ion and super-minimal stuff. see thread at:
i figured 165 miles / 5 days = 33 miles a day. a few less to start, up to 35+ when possible or necessary. i figure start at echo lake, go counter-clockwise, 1+ day to resupply at store near heavenly, 2+ days to resupply at market at tahoe city, 1+ day to echo lake and done. you walk right past both markets, so there's no point to do any caching. there are a couple of longer waterless stretches, so a bit of water needs to be carried sometimes.
i figured i'd be going solo, but it might be good to do it with someone else (plus an ipod!). but i can't do it july 19-24 - i have a family commitment already. the only july dates that could work for me would be over the weekend of 12-13. i had been planning on it for august, probably mid-august. september is a long hike in the sierra.
