I've managed to complete the first week of the October routine and have found that I can go a little faster if I try. For some reason today's 300m sets didn't record at all well but the general pace was good and I even achieved a 40second length which equates to 2:00min/100m although I didn't sustain it for the requisite 3 lengths. I think I have been a bit lazy in terms of effort while I have been focussing on technique. As the technique detail isn't working out I think Julian is trying to get my effort greater.
The lesson at the moment seems to be that a bit more effort can result in more speed over a few weeks. This makes sense, tempo and tartlet sessions work for running so why not in the water?
