48 hours

That's how long I was ill after a gentle lunchtime swim on Wednesday. It was a shame as I was starting to get the hang of things. My breathing was OK, my stroke length was OK (when I concentrated on it). Then I was hit by the urge to stop after about 30 lengths and a splitting headache. This turned into a sickness feeling which didn't any better when I was back at work. So I went home to bed fearing swine flu. Luckily I was only out of it for about 2 days. I guess I was fighting off a virus and the swim gave it some assistance.
