The fastest I ever ran was being chased by a bunch of drunk girls on a hen night party. I was already at what I thought was top speed when I rounded a corner and saw them. I thought I would be OK just dodging through them, but they pulled out these huge rubber mallets, dropped their shoes and sprinted after me. It was like being at school again, and I ran like the wind for a good 3rd of a mile with them in hot pursuit.
At the moment I probably run a mile in about eight or nine minutes. BUt I don't run on the flat, because there isn't any where I am.
