After a long rest set

This one like last week was tough. When I swam in my former life fly was not my best or worst stroke. Right now I am struggling with going further than 50 fly straight. At the end of this workout the first 25 of my 200 IM was easy, but really struggled after the turn. Both straight breast and the breast on the IM felt strong. I can tell I am not an IM swimmer.
