Another attempt at this set today:
400m front crawl warm-up
25 x 50m front crawl, target time 55s, rest interval 20s
200m front crawl swim down
Performance was much better than yesterday, but unfortunately I still failed to complete the set. Today my failures were on reps 12, 16 and 23, meaning I actually completed 900m at race pace. Perhaps because of a combination of my time off and the shorter rest interval than I was previously on, my reps were quite a bit slower than previously — generally around 51s or 52s.
USRPT distance this year: 28,850m
