10 x 100 @ 1:50
10 x 100 @ 1:40 pull, averaged 1:19-1:20
10 x 100 @ 1:30, averaged 1:20-1:21; this was a good set for me, although the last few hurt and my stroke began to fall apart. HR at the end was in the range of 175-180 (higher than my max. predicted). Last summer I made 15 of these swimming behind Ron Orris (who is still off on maternity leave).
12 x 50 @ 1:00, held :37 which is 400 race pace, felt surprisingly strong--I believe that the weight lifting and endurance training is helping
This summer I plan to make another assault on the 5:00 barrier in the 400 free. Next meet will be in Belton on May 16, my last chance to swim the 500 this season.
