Fed Up and Miserable

After a couple of good weeks of training I am now sitting up in bed at 10.30 on a Monday morning.  The first bug of the year has hit and I am fed up.

I am usually really healthy - I rarely get colds - but there has been a change in the weather and a nip in the air. the children have gone back to school, him indoors has had a bad head cold and now it has got to me.

What really annoys me is that after my lovely open air swim on Thursday evening I was chatting to a lifeguard about the benefits of cold water swimming.   Raising the immune system, opening the capillaries, blah blah.  I should have know better than to tell her that I never get colds.

The next day I was feeling a chill but went running anyway.  I felt really tired and chilly (and hot and sweaty) over the weekend and this morning have a bunged up nose and just don't feel right.

Here's the question though.  Is it a real cold brought on by:

a) swimming in the lido at dusk and getting chilled?

b) saying that I never get colds?

c) is it an inevitability at this time of year, especially as I have been dodging the lurgy from all and sundry over the past week?
or,
d) is it something to do with the fact that I have to start teaching tomorrow and I'm looking for an excuse not to?

Anyway, I am not going for my long run this morning.  I am sitting in bed writing the lecture that  I will inevitably have to give because I won't be so ill that I have to let everyone down.  I'll just have a good reason to be under par.  Rather than just being under par because I am.
