Genzebe Dibaba, Ethiopia: Track and field

Ethiopia’s star middle- and long-distance runner Genzebe Dibaba is the current world record holder for a number of indoor and outdoor distances, including the indoor 5000m, 1500m and two-mile. The 25-year-old says she will definitely compete in the indoor 5000m in Rio, and may also run the 10,000m. While the Rio games will be her second Olympics, she has yet to win a medal since she was injured in the 1500m four years ago in London. "This time I am going to write history," she told Pulse.
