Can anyone tell me what they think to his run walk approach . The reason I'm asking is I completed 6k a couple of days ago , I would like to eventually get to 10 injury free . For a coupe of days my legs have felt it , I'm no spring chicken (56) & could do with losing about half a stone , & was wondering if this would be a good way . Thing is , if I stopped to walk , I don't know if I'd get back going again because I used to prefer it when the walk intervals stopped in c25k & found it hard getting back in the run . Thanks for any info .
