So weird

The human body is a funny thing to figure out. I hit that downward spiral of hard training and fatigue then all of a sudden I'm moving strong again. Monday sucked. All around 100% blowy. Teusday morning I show up at the pool. I can't warm up, my arms are sluggish, my entire body ached. Well we started off with a set of 5x 300's on a 3:40 decsend. I knew it may hurt a bit. Well I causually rolled into my first 300 around 3:25. Second was 3:22, then a 3:19, 3:18 and finsished up with a 3:15. The entire time I felt like shit but, I was moving along pretty well. And yes, we moved onto 200's and 100's all sub 2:10 and sub 1:05's. Yesterday I felt like I was coming down with something. I took an easy 5.25 miler...35 mins...and a 2.5 hr bike where we sat above the 22 mph mark for most of the time. This morning...repeating 100's from 1:03 down to 57's. Still feel like shit. Somethings up here. I am not sure what but, this whole controlling fitness and understanduing recovery and gains is a bunch of snot. It's May. There is no reason why I am moving this fast right now. Compared to last year I am between 12%-18% faster (depending on discipline). However, I also see many others moving along pretty well too. Must be the mild spring or something. Who knows.
