Move your feet
I agree 100%. More if I could - the best way is to just get stuck into it and get some momentum. Though I think reasonably early on you step back and check you're doing things optimally.<p>One day I started running, just like the OP: I put on some shoes and ran. Eventually I followed a co-worker into a 5k race, 10k, half marathon, and eventually full marathon.<p>Much later I started a new job where one of my co-workers was an ex-pro runner. We went running one day and had to stop me right at the beginning: my running style was awful - I mean I got from point A to point B, but even with 1000s of kilometers under my belt I hadn't gotten good at it! It took me ages to unlearn and relearn to run.
