In 1980, a 23-year-old athlete from New York called Rosie Ruiz was the first woman who crossed the finish line in the Boston Marathon. Her time were very fast – just over two and a half hours – but almost immediately, the officials began to think something was wrong. Nobody remembered Rosie during the race and she didn't appear on videos of the runners while they were running. While the officials were investigating, two students gave them important information. The students were watching the runners from the side of the road when Rosie suddenly appeared from the crowd. In fact, Rosie didn't win the race. She only crossed the finish line first because she didn't run the course!
