This was a hard spike set!
The pool was very nearly empty so I can't blame anyone else for poor pacing. The warm-up was, I think, a personal best at 5:06min for 200m. On the first 2 'fast' sets I clearly beat 2:00min/100m across 66m which is great. After that I started to tire and by the time I reached the alternate slow/fast superset I was slowing even in the 'slow' sets. The final 4 'fast' sets averaged around 2:20min/100m and my arms felt thoroughly fatigued although I did my best to maintain form and keep a good 'feel' which was fairly successful as I averaged 22strokes/length.
