Buc, I used to be a swimmer. I was a sprinter (50 free, 100 free, 100 back), but I also swam the long-distance events in meets. I was on the Olympic training model until I realized that, in fact, I was NOT Olympic material and just swam for my high school, but on that model you swim five to six hours per day five days a week and three to four on Saturdays. In my book, swimmers are the most athletic and finely-tuned athletes in the world. I might be the teensiest bit biased, as might you.
Think about it this way: I swam all that time, was a three-year letter-winner in high school. I went to Emory for undergrad, where as you may know the swimming teams are perennial D3 dominators. I lived on the same hall as several swimmers that year...couldn't even keep up with them, let alone swim with them. Shows you what training PLUS natural talent can do for you.
Oh, and my graduate alma mater, Georgia, kills my other alma mater quite often in the pool.
At any rate, GO DAWGS!
