As you probably know, I’ve been swimming for this and the past 2 winters. I usually swim from November until March or April; when I cannot mountain bike.
Since last winter, I’ve been self learning the butterfly style. I think I finally have it going! It really just took a lot of practice and watching some videos on YouTube. I still get pretty exhausted after one lap on the 25m pool (50meters total), so I know I still need to work a lot on the style. But at least I think I don’t look ridiculous any more so I’m practicing it even more.
