The greatest, most charismatic snooker player of all time prefers long-distance running. He discusses drugs, breakdowns, victory – and his unexpected new career path

Ronnie O’Sullivan is driving over from Essex and says he’s bringing a friend. “Gloria’s with me. She’s brilliant. She picks me up when I’m properly on the floor.” It’s only two days since he won the World Snooker Championship – his sixth triumph in the sport’s biggest contest. Why would he be on the floor?

“You must be happy,” I say, when he arrives at my house – he pocketed £500,000 along with the trophy. He laughs. “You know what? I got up this morning and I felt a bit low. And I remembered every time I win a big tournament it puts me on a low. But I’ve accepted it. It’s just part of any high.” Typical Ronnie.
