My apologies, put it down to a bad day in the office.
'C25k' is the 'Couch to 5k' program designed to get non-runners, beginners, novices, whetever you prefer to call them, running. It's an 8-week run/walk program that buiklds up to 30 mins of running.
I haven't run for a long time because I fractured my spine in an accident and my right leg was left short by an inch and twisted. But I went through an op where my femur was re-fractured and an Ilizarov frame two years ago. Over the course of 12mths the frame is used to 'stretch' the two broken bones and new bone is grown. So my leg is now correct length again.
With that done I could contemplate running once again.
