The second session in this programme is awful. It's tough, long and I really do not enjoy it. Doing a fast set and then having to start the repeat the superset again is draining. I managed negative splits for 1600m but after that my arms were like lead and the second superset was slow. I did manage negative splits, which I think is a first, but the pace was glacial even for the fastest set.
Looking at previous sessions I did manage to control and raise the pace better today than in the past so there is slight progress. The pool was incredibly rough today, although I know I've written that before, so that increases the impact of fatigue.
