golfing slang - a shot that is hit thin, i.e. the club hits the middle of the ball and not the bottom, making it go low to the ground but travels (or runs) a long way down the fairway. Sally Gunnell was a 400m hurdles runner for Great Britain in the 80's/90's and won gold at the 1992 Barcelona Olympics.
