Runner Athing Mu won Olympic gold for the United States on Tuesday in the women’s 800 meters, highlighting an eventful day at the Tokyo Games. Mu, a 19-year-old from New Jersey, burst into the national conversation in June at the U.S. trials when her easy stride propelled her onto the Olympic team, and she matched her lofty standard on track and field’s biggest stage. Earlier, gymnast Simone Biles returned to competition and earned a bronze medal on balance beam, and Kevin Durant and the U.S. men’s basketball team beat Spain to advance to the semifinals against Australia.
