Who was the first runner to break 10 seconds for a 100 metre race?
Trivia Question Answer
Runner Jim Hines of the United States set a record of 9.9 seconds in a manually timed race on June 20, 1968 in Sacramento, California. At the Mexico City Olympics he recorded an electronically timed time of 9.95 seconds to win the gold medal. Because it was electronically timed, his 9.95 mark was considered faster than his manually timed 9.9. Jim Hines record of 9.95 seconds for the 100 metre race held a long time until it was broken by Calvin Smith of the United States who ran 100 metres in 9.93 seconds in 1983.
