Swim update 10x 100s Avg 1:43

I had a pretty solid swim at the gym. I was supposed to swim for 50 minutes, but I was really wiped, so I only did the main set. Even though I was tired I swam the fastest 100s I ever have. (AVG) I was able to keep it up without going crazy hard and being wiped for the next one. It feels like I have a better guage on how hard to push it or not. Feels good.
