I'm full of surprises

I barely got to the pool in time to get my workout in. I warmed up with a 200 pull, stretched real good and then got started with the 800. The first 200 went well, but then I started feeling it. I was thinking that the lack of sleep was finally catching up with me as I felt fatigue. I kept going and did my best to work it hard to the end. My (non-flip) turns were getting bad towards the end. When it was all said and done I checked my time and it was 13:48 - nine seconds better than my prior best time. What a pleasant surprise. Cooled down with a 200 and went home. Was going to work some more, but I'm pretty tired so off to bed I go.
