Ian Botham was/is a massive boozer too. Seen him in action with Viv Richards and with a few rugby boys when his boy played for Cardiff
I heard the best drunken sportsman story on the No Such Thing as a Fish podcast today.
At the 1953 Le Mans race, Duncan Hamilton's Jaguar team were disqualified because of an admin error that meant their car had the same number as another car. So Hamilton and his driving partner took off into town and went on the piss all night. The organisers realised that it wasn't fair disqualifying them, so they reinstated them. The Jaguar team manager went and found them at the bar and told them that the race was back on.
So Hamilton is brought to the track and helped into the car, massively pissed still, and sets off. At pits stops, his crew is pumping him full of coffee to keep him awake and to try and sober him up but he tells them that this was making him shake too much. So they start giving him brandy instead and just keep him a steady drunk.
During the race, a bird hit him in the face and broke his nose.
Despite all of this, he won the race and their team recorded the first average speed of 100mph for the entire race.
