Wednesday Night Swim

I'm still looking for a good workout tracking utility and haven't had much success to I'm just going to post the workouts and how they went.  Last night, Wednesday 2/25, I swam with TNT and was pretty beat from a rough couple days at work.  All I ate before swimming was a granola bar which is a lot less than normal.  Here is the workout:

Warm Up	8 x 50 Drills
Work Set	8 x 100 (50 @ Z4 / 50 @ Z2
	1 x 400 (300 @ Z2 / 100 @ Z3)
Cool Down	200

I was noticeably slower than the previous week but also haven't swam since last Wednesday.  Maybe there's something to that whole frequency thing.
