After an all day training session I went for an unstructured swim with no extra kit. I'd intended to do 300m sets but due to forgotten counts, changes of pace in the lane and possibly weak push-offs the watch mis-recorded in 5 of 6 sets. I also aimed for a 400m set but that suffered the same fate.
The best outcome was 400m in 11:08 which is still slower than Julian's time trial.
Altogether the swim felt like hard work. Perhaps not so surprising as I woke with a resting heart rate of 48bpm indicating that there is some background of fatigue. At least I've done it and got just over a mile in the bag. I knew it was time to stop as my rather negligible style was disappearing.
