What's the longest butterfly race you could swim?

Right now, about a 75.

Today? Probably a 200, and it would definitely not be pretty. In college, however, I went a 3000 LCM butterfly for time.

back in college I used to swim 3x 600 fly once a week. Now I could muster 200 yards and then run to the bathroom.

I'm with ImSpoiled - big differences in what I could swim, would want to swim and will swim. I am sure if I had to I could find some sort of slow setting on my fly and complete several hundred yards. I swim the 100 in meets and die like a dog but that has to do with racing. I've also swim 200s in meets a couple of times - no need to ever do that again.

Right now I COULD swim a 100 Fly.. years ago, I could do the 200... but no more. Now, would I actually LIKE to swim a 100 Fly??? That's a whole other story. I will leave that to FlyGirl!

Today? Probably a 200, and it would definitely not be pretty. In college, however, I went a 3000 LCM butterfly for time. Wow, is that legal? It might fall under torture lol.

Don't ask Dennis Baker this question.

Dennis' answer is off the chart. I've done the 200 fly in a meet and I would do it again if I wanted to. I've done as much as a 600 fly in practice.

I know I could do a 400. Anything longer might get dicey!

I can swim VERY slow fly pretty much indefinitely(but it is really ugly.My reasonable looking fly is only about 100.)I can swim butterfrog much faster than my ugly stroke and do in indefinitely also(indefinitely means until I get bored,maybe 1500 if extremely motivated.)
