Athletics at the 1904 Summer Olympics – Men's 110 metres hurdles

This was the third appearance of the event, which is one of 12 athletics events to have been held at every Summer Olympics. None of the hurdlers from 1900 returned. Edwin Clapp was the 1903 and 1904 IC4A champion and the American favorite; he entered but did not start. Thaddeus Shideler had matched Alvin Kraenzlein's 120 yards hurdles world record. Frederick Schule was the 1903 AAU champion, while Frank Castleman was the 1904 winner.[2]

Australia made its first appearance in the event. The United States made its third appearance, the only nation to compete in the 110 metres hurdles in each of the first three Games.

There were two rounds: semifinals and a final. There were two semifinals, one with 2 runners and one with 4 runners after withdrawals. The top two runners in each of the semifinal heats advanced to the 4-man final.[2]

These were the standing world and Olympic records (in seconds) prior to the 1904 Summer Olympics.
