Edward Spencer, weighed 18 stone in June last year and was finding lots of excuses for not keeping fit. He said "One day I was feeling a bit depressed and decided to go for a walk, I walked to Wood Green and bought a book. After walking to Wood Green I decided to walk home and on my return I decided that I quite enjoyed walking, I was sweating like a pig and thought that maybe I might have lost some weight! I went to Argos and bought some scales."
Over the past 7 months he lost 4 stone through running & is now going to run the entire Piccadilly Line from Uxbridge to Cockfosters in a day.
You can follow his progress including a Google map of the route & his training on his blog WalkthePiccadillyLine.com. Edward estimates the run ,which is equivalent to just over one and a half marathons, will take him between 10 and 12 hours.
