The men's 800 metres was the middle of the seven men's track races in the Athletics at the 1964 Summer Olympics program in Tokyo. 47 athletes from 32 nations competed. The maximum number of athletes per nation had been set at 3 since the 1930 Olympic Congress. The first round was held on 14 October, with the semifinals on 15 October and the final on 16 October. The event was won by Peter Snell of New Zealand, successfully defending his 1960 gold medal (the third man to do so), and completing the first half of his 800 metres/1500 metres double. Bill Crothers of Canada took silver, the first 800 metres medal for that nation since 1936 and matching Canada's best-ever result in the event (silver in 1932). Wilson Kiprugut's bronze was the first medal by Kenya in any event; Kenya would become a frequent fixture on the men's 800 metres podium. Summary The runners used a crouch start without blocks and a single turn stagger start (breaking after the first turn). Returning to the final from four years earlier were defending champion Peter Snell and bronze medalist George Kerr. While Snell started strongly, he found himself in third place at the break, led by aggressive front-running by Wilson Kiprugut. As others moved forward, Snell found himself boxed along the rail, so as the runners came onto the home stretch he had to slow to come out the back of the box, then as the bell approached, he glided along the outside to catch up to Kiprugut and Kerr in the lead. With free running room, Snell kept going, taking the lead on the penultimate turn. After establishing a three-metre lead, he held his position, even extending it a little to take the repeat gold. Down the backstretch, Bill Crothers made his way around Kiprugut while Kerr was trying to chase down Snell. Crothers came off the final turn with more speed, passing Kerr on the home stretch. Kerr began to struggle. Snell was too far ahead for Crothers to catch, but Kiprugut closed down on Kerr, passing him and sealing the bronze medal with a dip at the finish. Snell became the third to defend his 800-metre title after Douglas Lowe and Mal Whitfield. The feat would not be accomplished again for 52 years until David Rudisha repeated in 2016. Kiprugut won Kenya's first ever Olympic medal, unleashing a floodgate
