PARIS — 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. "I can't tell you I'm going to get the gold medal in every event," Hassan said Wednesday. 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.
