I started the couch to 5k last Thursday and have Day1 & 2 done. Day 3 is tomorrow when I will also restart TFR..... I expect to be far more tired but will see how it goes!
Good luck - I think you can apply still for 2012 London Marathon! I understand also that the London Olympics are looking for people for the opening ceremony who can walk around the arena waving countries flags - my nephew has just been given a place!
I'm on Day 6 of LT and did day 1 of C25K last night found it ok tbh ...felt a bit wobbly at one point so instead of jogging as they were suggesting I decided to walk for longer and was then ok for the next stint of jogging x x x Go for it you never know unless you try x x x
