Caroline Wozniacki finds training for New York Marathon has put her mind off not getting married

Determined Caroline Wozniacki has told how training for the New York Marathon has put her mind off being dumped by former fiancee Rory McIlroy.

The Danish tennis star will be one of the tens of thousands of runners pounding the streets of the Big Apple this Sunday – exactly when she was due to get married.

However Caroline, 24, who was left devastated when the Northern Irish golfer cruelly called off their wedding earlier this year, said running has helped with the heartbreak.

Training: Caroline getting ready for marathon this weekend

“I think you can never feel too sure in life. You can’t really plan ahead because you never know what’s going to happen tomorrow,” she told the New York Times.

“To be honest, this half of the year I’ve been great tennis-wise, and the running and everything has definitely helped me with everything.

“It’s cleared my head, but also it’s helped me physically, and I feel stronger on the court. So it’s been a great thing for me. It’s a nice challenge.”

But Caroline admits training alongside her tennis career hasn’t been easy – and she now fears whether she’ll be able to run the full 26 miles for charity.

She added: “I was like, ‘I’ve got this; I’m cool; it’s going to be easy.’ And then I started running more, and in Asia I felt like, ‘Where am I going to run?’

“I started panicking a little bit — uh oh, it’s getting close, and I don’t know if I can do this.

“I think playing [tennis] and sprinting in intervals is really tough, and you feel sore in your whole body.

“And running, the calves are what feels it the most the same day. But at the same time I don’t feel particularly dead whenever I run because you get into a rhythm, you breathe, you find a breathing pattern.”
