Manuel Plaza

Athletic career Plaza was inspired by runners such as Martiniano Becerra, Benjamín Flores, and Juan Jorquera, which led him to pursue athletics. He began training alone in the ellipse of Parque Cousiño, now Parque O'Higgins, and joined training sessions with established athlete Alfonso Sánchez, who encouraged him to compete.

His first race, at age 16, was a lap around Parque Cousiño, which he won. As a federated athlete, Plaza was a member of the Centenario Athletic Club, Pietro Dorando, and joined Green Cross in 1922.

During the 1920s, Plaza excelled in long-distance events in South America. Besides his silver medal in the 1928 Amsterdam Olympics, he placed sixth in the marathon at the 1924 Paris Olympics. At the 1923 South American Championship, he finished third in the 5,000 meters and second in the 10,000 meters. He went on to win four gold medals in each of the next three editions of the championships (1924, 1926, and 1927) in the 5,000 meters, 10,000 meters, cross-country, and 3,000 meters team events. Plaza also won the cross-country and 32 km races in 1933.

He was Chile's flag bearer at the opening ceremonies of the 1924 Paris and 1928 Amsterdam Olympic Games.

A myth circulated that Plaza finished second in the Amsterdam marathon after getting lost shortly before reaching the finish line, a version he himself promoted.
