FILE - In this Aug. 8, 2015, file photo, Australia's Bronte Campbell, left, and her sister Cate Campbell, right, look at results after a women's 50-meter freestyle heat at the Swimming World Championships in Kazan, Russia. The two are both leading medal contenders heading into the Rio Olympics, though they quickly point out this isn't one of those sibling rivalries from the Serena vs. Venus Williams mold, the kind that stirs mixed emotions when they inevitably face each other for the same prize.  "It's very different (than) Venus and Serena because we're not playing against each other on the tennis court," Bronte Campbell said Tuesday, Aug. 2. "We're swimming in a swimming pool against six other people in the race. I'm not really racing against Cate. I'm racing against myself and trying to do my best race." (AP Photo/Michael Sohn, File)
