After a year of parkruns I do them no quicker than when I started - in fact sometimes more slowly than the early ones. In those I got down (!) to the high thirties from my initial 40 minutes but now I have slowed sometimes to 41-42 minutes. In my eighties, I can't expect to be anything near quick but I ought to do better than that. I've tried a number of pacing aids - Ratesetter, C25K+ podcasts, my TomTom watch - but the overall effect seems to be to give me the impression that I'm doing better than I actually am. I try to run twice during the week but usually have to settle for once, sometimes over the parkrun course, sometimes over rough ground, with tree roots and grass tussocks to make it harder. I understand that 'the main thing is you've done it', as I am told so often, but some suggestions on doing it better would be welcome.
