Awesome! Well these are the two sites I sued to get my c25K started:

Cool Running :: The Couch-to-5K Running Plan

Podrunner: Intervals - Free Workout Music from dj steve boyett

Dj Steveboy is awesome bc you can dowload a podcast of every week onto your ipod. It guides you week by week. It's electronic music...but it keeps you pretty motivated! Every weekly podcast signals when you should walk and when you should run. I love it bc it's a no brainer. Good Luck Ladies!!!
