Nike+ is awesome
This was the straw that broke the camels back. For my birthday I asked my girlfriend for Nike+. It is a system which has a sensor in your shoe and this connects to either a iPod nano, iPhone, iPod touch or Nike wrist band. This collects data on distance run, time, calories burnt etc.
The best bit for me was the group challenges (of which there are hundreds). I joined the premiership challenge for Tottenham (Come on you Spurs) and each run you complete upon iPod syncage (if that is a word) it will update the challenge table for your team. I find this a great motivation to help your team become the best. Also if you decide not to run one evening you feel that you are letting others down which is a nice reverse psychology method to make you continue running rather than bailing out.
