Nine of us swam in Lake CDA this morning (the lake temps were just under 52 degrees) and after the first couple of minutes it was not so bad. We swam a 1.2 mile out and back course and afterwards most of us felt that we were ready and able to jump back in and do another loop, even with the somewhat choppy waters.
I wore my neoprene cap under my swim cap, the top that was recommended earlier, and my newly purchased booties under my Blue Seventy booties. I was comfortable throughout the swim. The hands were a bit cold and I suspect the feet would be as well after a second loop but I felt it was nothing that I could not handle.
After this morning's swim I will no longer fret about the lake temps. It may not be pretty, for me at least, but it is definitely doable!
