Wheee...other runners!!
Karenmae, there are a lot of programs out there that will get you from being completely inactive to being able to run for about 20-30 minutes at a stretch in about 9 weeks. Are you doing one of those? Just do a search for "Couch to 5k" and you should come up with several. There's even one that has podcasts to tell you when to run, when to take a walk break, etc. - that's the one I did, and it worked out great! I don't know if I'm allowed to post the links here, though.
Can you PM me the link? I am dying to start running (everytime I start I think i burn myself out by "trying too hard" and I quit).. Thanks!
