I've been running on & off for 6 months & at the beginning of the year got up to doing 8 miles - 10 minute miling but that's fine by me. Then I got injured & went on holiday. Since I've been back, although I've been able to make myself go out and run, (3 or 4 miles), 3 or 4 times a week, I keep stopping to walk. My legs don't feel tired, so I don't think its really my fitness, just my head! What can I do to keep myself going - I trying slowing down to an even ploddier plod, but then I just walk. Once I've started walking, that's it I keep doing it every couple of minutes. So frustrating. The thing is I want to do the Plymouth half at the end of May and am worried this will hamper my schedule.
