Peaty believes he is in a “very good frame of mind” as he makes his return in London.

He won gold in the 50m at the Edinburgh International Swim Meet a month ago but finished fourth in the 100m, beaten by 18-year-old British junior world champion Filip Nowacki.

He’s settled in his family life too, having married model Holly Ramsay, the daughter of TV chef Gordon, in December.

“It gives an incredible amount of peace, the life we’ve got together,” he says. “But also that I can do this incredible thing which I call sport.”

He adds that swimming “will humble you” and is a “hard path”, but “what makes that path a lot easier is having my wife, my son and friends around me”.

Peaty credits the support of his famous in-laws, too, with whom he completed his debut triathlon as part of Team Ramsay last August.

But thinking back to his wedding speech, he concedes Gordon probably won the prize for best toast of the day.

“It was always going to be hard to beat Gordon’s speech,” said Peaty.

“Having her [Holly’s] family there for the support and the love they have for us is incredible but Gordon is never going to find it hard to make the room laugh.

“He was able to bring the room together because that’s what a wedding is in my eyes – that you bring these people from all areas of your life, you bring them together.”

Chef and restaurateur Ramsay, 59, has completed a number of Ironman and ultramarathon events in recent years.

“[He’s] very inspiring,” Peaty said. “I think for him it’s obviously a very different way of life in terms of the business he has to do and the businesses he has to run.

“I take a lot of guidance. I look up to him a lot… in [terms of] sport, he knows the game is the game, that it doesn’t lie. But it will humble you and you’ve got to work hard for those results.

“I know that whatever I learned through sport, those are the skills I can take into the rest of my life as well.”
