I just started the Couch to 5k running plan last week. So far so good. I am on the second week.
I find it is easier to get through it if I have upbeat music on that I can try to keep up with and not stare at the time on the clock. It's a 9 week program so hopefully by March (if things warm up here) I will be able to start running outdoors. I've never been an active person or a very healthy eater, so I'm trying really hard to be.
I live in a beautiful place that offers many areas for hiking and biking and I'd to be able to experience that rather than sit on my butt all day doing nothing!
