I recall there were quite a few people missing from the start line that morning as there were a couple of big local races taking place.

I thought my start was slower than usual, but when I reached the bandstand on the first lap I noticed I was passing people who I would normally only see in the distance - I assumed they were just having an off day, but resolved to keep in front of them.
I've yet to come within even 20 seconds of that time, and can't see the PB ever falling.
I'm too much older, fatter and generally slower now
It wasn't until I got to the end that I realised that something was up, my watch seemed to be saying I was over 30
seconds quicker than usual - the SMS said it was closer to 40 seconds with a time of 21'44!
