I've taken up running a few weeks ago, as I am trying to get back into shape. Everyone knows its nicer running with someone else, so when I was told of an event called parkrun happening near me every week on a Saturday I jumped at it. Parkrun is running 5 kilometers, they time it and post lots of stats about your time and how you did in comparison to everyone else. If you live in the UK and is interested, sign up at http://www.parkrun.com/home
Its free by the way
My time was 25 minutes and 43 seconds.
