In today’s example of “this is why I blog”: as I implement Zone 2 training for doing distance running again I was lamenting not having done so for my 2013 marathon training. According to my race recap post it turns out I did implement Zone 2 training. Well, I thought I had anyway. Looking back over the data however it is pretty clear that I did not. That’s not just a question of my race performance, where I threw all of that to the wind anyway, but also looking at the training data from that era as well.
