What is Couch to 5K?

Couch to 5K is a running program at coolrunning.com. It's a 9-week plan where you alternate between walking and running, and the runs get longer each week. In the first week, you alternate walking for 90 seconds and running for 60 seconds. By the end of the 5th week, you can run for 20 minutes at a stretch, and at the end of 9 weeks, you can run 5k (or 30 minutes, which is less than 5k for me!). Couch to 5K itself is just the running plan, but there are podcasts you can download for your MP3 player with good music and they tell you when to run and when to walk. I use Robert Ullrey and Podrunner.
