The women’s marathon opens the final day of competition, but that 42.2-kilometer race, which begins and ends at the historic Brandenburg Gate, is only the beginning. The women go for the gold in three other events, including the long jump, four-by-400-meter relay and the 1 500 meters.
Anna Willard of the United States is one of three Americans to make the 400-meter finals and she told VOA Sports about her plan for Sunday. The men will also be busy Sunday with four gold medal events. They begin with the javelin throw, followed by the 1 500 and 800 meters. American Nick Symmonds won his 800-meter semifinal heat, despite having three runners in front of him trip and fall down. The last event of the Championships will be the final of the men’s four-by-400-meter relay.
