Body bites back

The result was inevitable. The last week or so I've been pushing on through with my training with little regard to the cold/fever/blocked sinusses symptoms I've been suffering from. Today my body said enough is enough and shut down on me. I did the usual 11.75 from the Dowd this am and actually felt fine throughout, but as soon as I got to work I felt rough and had to come home. Just feeling dog tired, very queasy and sinusses are giving me lots of grief. Similar actually to how I felt a few weeks ago in England when I had to miss that race. Hopefully my recovery time from this will be equally fast...
