I hadn't swum much in November as the running miles increased but as this was a run rest week it seemed wise to do second swim. As usual it felt like hard work but I worked at a front quadrant approach and having a tiny glide element. I also used my legs a bit more, mainly to try to stop them from sinking and acting as a brake. During the session I had to move into a 25m section and that is always a lot easier than the full 33.3m as 'breathers' happen more frequently. Conversely at one end there's nothing to push off from so you have to build up speed from a 'splosh'.
The timing was good with a pace under 4min for 100m for the first time in ages. Is this due to the swimming class, a rest week or merely a chance outcome? It might, but hopefully not, be a timing error.
