Emil Zápotek is the only athlete who has managed to win gold in the 5,000, 10,000, and marathon at a single Olympic Games. The Czech athlete dominated all three events, including his debut over 26.2, at the 1952 Olympic Games in Helsinki. In fact, Runner’s World named him the greatest runner of all time in 2013.

Hassan said she was inspired by Zápotek when she made her decision.

“I’m curious what’s going to happen,” Hassan said. “My big focus is just how I’m going to complete [the events], how I’m going to recover, especially for the marathon.”

Here is the timeline of Hassan’s schedule in Paris.

August 2: Round 1 of the 5,000
August 5: Final of the 5,000
August 9: Final of the 10,000
August 11: Marathon
