Caroline Wozniacki proved she is more than just a one trick pony as the tennis star ran her way to a great time at the the New York Marathon over the weekend, and Serena Wiliams was on-hand to celebrate with her friend and fellow star at the finish line.
Just a week after failing to win the WTA Finals in Singapore - she was knocked out by eventual winner Serena - Wozniacki was donning her running gear in chilly temperatures for the race around the 'Big Apple.'
It turned out to be a hugely successful day for the Danish star as she clocked an impressive time despite a lack of Marathon-distance training due to her tennis commitments; 3;26;33 to be precise.
It wasn't just Wozniacki's time that was impressive either, the 24-year-old managed to raise an amazing $81,000 for the children's charity 'Team for Kids' as she competed alongside thousands of competitors in difficult conditions.

Clearly impressed was current female world no.1 tennis star Serena, the powerful American embraced Wozniacki after picking up her medal as it became clear there were no hard feelings between the pair following their match in Singapore.
Having been denied her first ever Grand Slam title in the US Open final by Serena just two months before, Wozniacki again came unstuck against the 18-time Grand Slam champion in the last-four of the WTA Finals, despite taking a set lead.
The younger Williams sister went on to claim her fifth Finals title but thrashing Simona Halep in straight sets in the Singapore climax.
Wozniacki and Williams have been friends for some time and the latter was also there to comfort the Dane after her high-profile relationship with Rory McIlroy was ended by the golfer earlier this year having already sent-out invites to their wedding.
Friendly on-court foe
Serena took to Twitter to make her admiration for Wozniacki clear after her latest feat at the New York Marathon: 'Is it normal to when someone finished marathon? So proud of you caro,' she said to her followers on the social media site.
Now that the marathon is over and done with, the duo have the opportunity to spend some more time together, especially considering the tennis season has finished for the year.The Finals were expected to be their last competitive action until preparations for a new season - starting with the Australian Open - will take focus in the early part of 2015.
The 33-year-old Serena is a nine-time winner Down Under when you combine singes and doubles results, while Wozniacki has only ever surpassed the quarter-finals once in Melbourne.
