Andy Murray suffered “violent diarrhoea” in front of a tester during a drug test at the Australian Open. “It’s a horrible moment… and for him as well,” he recalled.

The three-time Grand Slam winner said the incident happened in a “tight cubicle” during his playing career which ended at the Paris Olympics last summer.

“A few years ago, I played a first round at the Australian Open,” recalled the Scot, 37. “I played four hours and 40 minutes or something, and I won.

“At the end of the year beforehand, I’d been having some issues with cramping so in that match it was the first tournament of the new year, four hours and 40 minutes and I was nervous about potentially cramping again so I’d been nailing the energy gels and sports drink and pickle juice.

“I finished the match, won the match and, when I came off the court, I got asked to join a drugs test straight off the court and I was like: ‘F***ing hell, really?’ but I was in a good mood because I’d won.

“So I went straight from court and I needed to go to the toilet. So I went to do the drugs test. It’s not the most pleasant experience. I’ve gone into the cubicle with the guy and it’s a tight cubicle.

“Obviously, they ask you to pull your shorts down below your knees and lift your shirt up above your stomach so I assume they can make sure it’s you peeing into the thing. As I start to go I’m like my stomach has gone here.

“And I’m like I’ve got to sit down and I’m sitting with a guy staring right in my face having like the most violent diarrhoea in front of this guy. It’s a horrible moment… and for him as well.”

Since retiring, Murray has played golf, went skiing for the first time and coached Novak Djokovic at the Australian Open.

Speaking to the Sporting Misadventures podcast, he said: “I’ve not missed playing at all. I’ve hit tennis balls like three times since the Olympics in Paris and I have no desire to do it right now.

“Maybe at some stage I will want to play and the times that I did I was terrible. I played so badly. But I actually enjoyed it. I didn’t find it frustrating or anything.

“I hit with some friends and just enjoyed playing even though I can’t play anymore, I can’t move, my shoulder’s gone, I can’t serve. I just enjoy hitting balls occasionally but it’s not something that I miss or that I really want to do.”
