The Athlete's Diary, by Stevens Creek Software, has both a PDA and desktop versions, and of course they talk to each other, but they can also be used separately. The program is set up as tri-specific, but you can add other things you do like yoga or strength training, though it won't capture specific weight and rep data. You can get it at www.stevenscreek.com. I've been using it for a little over a year and I like how it works. Hope that helps.

I am using Runners Log $ 10.00 I got it at Palm.com. You can try it for free for 30 days. Easy and simple to use.
