bit of a long shot this, but I ran my first half marathon in 1988 at the Great North Run (which I think was still run in July then) when I was 18, I then ran it a few years later in 1991...much slower and could barley walk afterwards, certainly couldn't bend my knees!
I'm pretty sure my 1988 time was about 1hour 48mins, no idea what my 1991 times was (just remember it hurt and was slower).
Is there anywhere that has archived previous year's results? or does anyone still have their own copy of the results that I think used to get published in the paper?
Now that I'm 43, it's doubtful that I'll beat my 18 year old self, but fancy having a crack at my '91 year time next year
