Anyway, today I swam rather briskly but briefly at Lifetime Fitness. After 600 meters of warming up, I did 3 sets of 400 each at level 3-4 with only 30-seconds rest. The whole routine (including cool down) took all of 38 minutes!
It’s the first time I used the new (replacement) 910XT for a swim. BTW – some folks pay attention to the SWOLF score. I don’t. Apparently, SWOLF adds the number of strokes to the time (in seconds) it took to swim a lap. My SWOLF score in a 25-meter pool is around 37 or 38 which is satisfactory but not great.
