Sifan Hassan is an Ethiopian-born Dutch middle- and long-distance runner. She is most recognized for her versatility in running championship and world leading performances in widely disparate distances. She completed an unprecedented triple at the 2020 Tokyo Olympics, winning gold medals in both the 5,000 metres and 10,000 metres and a bronze medal for the 1,500 metres. Hassan is the only athlete in Olympic history to win medals across a middle-distance event and both long-distance races in a single Games. She is only the second woman to complete an Olympic distance double.
