This was the second time the event was held. None of the 1896 runners competed in 1900. American Arthur Duffey had recently won the AAA Championships and was heavily favored. Unofficial world record holder Isaac Westergren of Sweden also entered the competition. No athletes from France, the host nation, competed. Australia, Bohemia, India, and Italy were represented for the first time. The 1900 competition was one of only two Olympic Games where the men's 100 metres was not the shortest sprint, with the 60 metres being held in those two years.
Arthur Duffey in the first heat of the first round and Walter Tewksbury in the second heat of the first round set new Olympic records with 11.4 seconds. In the third heat of the first round Frank Jarvis equalled the unofficial world record with 10.8 seconds. In the second semifinal Tewksbury also equalled the world record with 10.8 seconds.
Competition format
The competition consisted of four rounds: heats, semifinals, a repechage, and a final. The top two runners in each of the six heats advanced to the semifinals. Those 12 men were divided into 3 semifinals of 4 runners each. The 1st-place runner in each semifinal advanced directly to the final, the 2nd and 3rd place runners went to the repechage, and the 4th place finisher was eliminated. In the 6-man repechage, only the winner advanced to the final and everyone else was eliminated.

Semifinal 2
Tewksbury equalled the world record, the second runner to accomplish that at the Paris Games, with Leiblee six inches behind him. There is some question as to whether Dörry started the race, but he did not finish it.
