I did try an earlier, battery eating, version of the Active 10 app (years ago) but you've been nudging me to give it another go...
And I am glad I did because I've had a bit of a revelation... this afternoon I went out (for a run) and decided to run the Active 10 pace checker in my warm up walk and found that a comfortable pace for me *is* enough to count as brisk walking, even though the indicators I've seen previously had suggested it wasn't (and a walking pace that achieves those indicators is - at best - disagreeable for me... and, I now realise, one of my major obstacles with C25K first time round)
