After learning of a friend who has completed C25K I'm seriously thinking about it. I have ALOT conspiring against me...nearly 48 years old, technically morbidly obese according to all the BMI charts, and I've been asthmatic all my life (even before all the weight gain) and I broke my left tib & fib a few years ago which has left me with a ropey ankle and the need for insoles to correct my gait. Maybe I need to see a vet! All that said I'm really keen to give this a go, but really nervous about starting. Keen to hear from others who may have been in a similar boat!
