I didn't vote, because I have no fear of either of those events, and I have "raced" them all. I say "raced," because my times weren't exactly lightning speed- especially my 200 fly. Having swum a non-stop 2000 fly, I know I can swim 200 fly with no problem. Racing 200 fly is another story. The key for me is using pwb's race strategy to make sure the piano doesn't come crashing down on my back!
