It's the weekend and my body is starting to rebel like a naughty schoolkid.

I wasn't planning to do any running anyway, but my old, aching bones weren't taking any chances.

I woke to find my neck in spasm, and the pain spreading through my shoulders. I could hardly move my head.

I felt as flexible - and as useless - as a shop window dummy.

There was no way I could run, even if I wanted to. A perfect excuse, I thought, although that was counter-balanced by the dull, nagging pain in the neck (and I'm not talking about Rafa Benitez).

Sunday wasn't much better, although Sharon and I went for a long walk to keep the heart pumping.

Then the body struck again.

An ankle injury during my days as an American Football player (yes, I was one of those with bigger shoulderpads than Pamela Anderson), has bothered me for more than 20 years.

It swells up and practically gives in about once every six months. Yes, halfway through my walk, my ankle decided to notch Sunday, 14th March 2010, as the day of pain.

I ended up hobbling the rest of the way home, not in huge pain but more discomfort.

If I'm to run in this 10K, this body had better start behaving...or else.
