Well, I didn't break any records but if I'm patient I'm sure it'll keep coming. My watch actually got so many laps that it stopped recording them. But I was able to accurately record the following: 75, 75, 74, 75, 75, 75, 76, 76, 75, 75, 75, 76, 75, 76, 75, 68. Those were 400s punctuated by running from the finish line to the 400m start of lane 8. For the first half of the workout it was a brief jog and then I started again: 12-14 seconds. By the end of the workout, it creeped to 15 and eventually 20 seconds as I went really slowly.
