I DID IT!!!
I finished my 1 mile swim-- that's consecutive 35 laps of freestyle & backstroke in a 25 yard pool! I feel great. I never thought it's doable! After my 14th lap, I entered "the zone" (like a runner's high); I started feeling numb. My right calf began cramping though around 21st, but I had to keep going before my 1 hour limit's up.
Okay, after this class is over, biking next?
:o)
