I did a length of butterfly today, my first 50m long course of fly ever. It was rad and tiring at the same time. What else was rad was doing fly with 2 kicks after the catch, which helps kind of a lot cuz straight butterflying for 50m is way tiring. Other than that, I went through a bunch of the usual drills, zipperswitch with flutter and fly kick, some kicking, back and breaststroke, and some easy freestyle. Total distance: 1300m.
