I've kept running all through the winter, through the cold and generally horrible weather, although it was often a bit of a plod. I'm now on a conscious effort always to do at least 30 mins on every run. This week has been the first where I've felt properly back in the zone - the one where you get into your stride, do the 30 mins (or more) and just feel that you can keep going, and going, and going. This is still a way short of the "flying" zone where you up the pace to the point where you feel you're flying, and just keep going. Not there yet, but I've been there before and will be again. Now let's have some nice weather to do it in.
