Err umm .... very peculiar

Wow, Sunday was a fabulously warm and sunny day, a fantastic day for a bike ride.   I passed several cyclists on the normally quiet Sunday roads, it was brilliant.   After a pleasant 40 mile cycle, I cut short the ride and detoured home as I started to feel slightly peculiar.  I showered and changed, but then had to go to bed to lie down, all of a sudden I had no energy.  

Zonk !!!!! I was out for the count. I woke up an hour or so later running a temperature of 101 f, terrible stomach pains and a stinking headache.  I managed to crawl into work today, fortunately my temperature has gone, alas its knocked training out for a couple of days.
