Tennis stars Serena Williams and Caroline Wozniacki were both in the Bahamas this weekend and as one tends to do when in the Bahamas they both decided to hit the pool in bikinis. That is, when they weren’t competing in a triathlon. That’s right, Wozniacki just ran in a marathon and now she’s doing triathlons. Girl’s a machine. Plus, who knew Serena Williams was also into that sort of thing? So much to process here.
