How far does a professional tennis player run during a tennis match? It varies, depending on playing style, according to data that IBM and SI.com teamed up to track and publish data from the current Australian Open.
Their research reveals that, among the top men, David Ferrer, who is known for his speed and agility, covers the most distance. Through three rounds of the 2015 Australian Open, Ferrer had run approximately 10,000 metres.
On the other end of the spectrum, top-ranked Novak Djokovic had covered less than half that distance, somewhere between 4,000 and 5,000 meters through three rounds.
SI.com reports that this is because Djokovic tends to play closer to the baseline, while Ferrer plays farther back.
Apparently running less can sometimes be a good thing, as top-ranked Djokovic won the tournament, while Ferrer was eliminated earlier today in the fourth round.
A similar analysis conducted at the 2014 U.S. Open found that Caroline Wozniacki ran more than twice as far as Serena Williams (9,709 metres for Wozniacki, 4,509 for Williams) to make it to the final. Williams defeated Wozniacki convincingly in the final. Wozniacki famously put all that running to good use two months later when she ran her first marathon, New York City, in 3:26:33.
