Tennis star Caroline Wozniacki plans to play a full tournament schedule this fall while fitting in time to train for the New York City Marathon.

The former No. 1 player said Thursday that she long had wanted to do a marathon and decided before Wimbledon that she could pull it off this year. She says seeking this challenge wasn't an attempt to distract herself from her personal life — golfer Rory McIlroy broke off their engagement in late May.

Wozniacki says she typically runs for a half-hour at a time in training and plans to add hour-long runs to prepare for the 26.2-mile race. The 24-year-old Dane says the longest she's ever run is 10 kilometers — less than a quarter of a marathon.
