I'm not that great of a swimmer, but today after work I managed to do one pool length of freestyle - last week I could only manage about 1/2 a length of the pool, my gosh, swimming is hard work! I did other strokes 3 other times, but freestyle is what I'm shooting for. I think that it will take a year and a half to get up to a half mile. That's a lot of laps in the pool at around 100' per length to make up a half mile...oye.
I see a new challenge in my future...keep on swimmin'-swimmin'-swimmin!
