PARIS (AP) — Attempting to defend her 5,000- and 10,000-meter titles at the Olympics isn’t enough for Ethiopian-born Dutch runner Sifan Hassan. She also will push herself in the ultimate test of endurance, adding the marathon to her program at the Paris Games. And she’ll have roughly only 35 hours between the end of the 10,000 and the marathon. But now she can match Emil Zatopek’s exploit from 1952, when the Czech runner swept the 5,000, 10,000 and the marathon at the Helsinki Games. When Hassan started winning multiple events earlier in her career, she learned about Zatopek and watched a film about him.
