<p>Former world number one Caroline Wozniacki knows just what to expect when she steps on a tennis court, but tackling the New York City Marathon is another matter.<br /><br /></p>.<p>"I'm a little nervous," the Dane admitted on Wednesday as she looked ahead to her first crack at the 26.2-mile distance on Sunday.<br /><br />"This is the farthest I'm going to run so far. I think it's going to be an unbelievable experience. The New York City Marathon has always been on my bucket list."<br /><br />Wozniacki decided to make the fantasy a reality back in June -- not long after the break-up of her engagement to golf star Rory McIlroy.
