Twenty-six-year-old Emil Zátopek won the gold medal in the 10-kilometre run on the first day (his third race at that distance). On the second day he added a silver medal in the 5 km run. Czechoslovak canoeists were also very successful (gaining three gold and one silver medal), Jan Brzák-Felix successfully defended his medal that he had won 12 years earlier in 1936 Summer Olympics with another partner, Václav Havel and Jiří Pecka won a silver medal using a 12-year-old boat from the 1936 Olympics. Boxer Július Torma won the gold medal in the Welterweight class, although he had injured his left arm before the semi-final. Women's gymnastics team also secured gold medals, but this victory was overshadowed by the death of their teammate Eliška Misáková, who succumbed to polio in London.
