 Timing issues on the 500 m were a problem within the sport until electronic clocks arrived in the 1960s; during the 1936 Olympic 500-metre race, it was suggested that Ivar Ballangrud's 500-metre time was almost a second too good.Finland won the remaining four gold medals at the 1924 Games, with Clas Thunberg winning 1,500 metres, 5,000 metres, and allround.It was the only time an allround Olympic gold medal has been awarded in speed skating.
