Well I'm 70, overweightish & a grandma to six gorgeous girls, whose always said " I've never liked running & I'm not starting now! Always been more of a walker really, while my daughters all took up running, recommended C25K & streaked into the distance. We happened to have moved next door to a gym & I felt that I should have a go at running rather than just walking on the treadmill.got to wk3 run 2without too many probs other than aching joints, really surprising myself in the process! Then following a busy wkend looking after Gdaughters no 5 &6. Thought that I should finish wk3 today, with a flourish in their local park, first outside run, disaster strikes,was so out of breath had to walk a bit during both 3 min sessions & sort of hobbled home at the end. Is this what they mean by a bad run? Feel a bit demoralised but will have another go on Thurs. I'm NOT giving up now!
