America's top hurdler was Edwin Clapp, IC4A champion in both 1903 and 1904, who entered but did not appear. This left the favorites role to Thad Shideler who in June had equaled Al Kraenzlein's world record of 15.0, only to see it not stand up because only two watches registered a time. Fred Schule won the first heat, and Frank Castleman nipped Shideler in the 2nd heat. This gave the final the last two AAU champions (Schule - 1903 and Castleman - 1904) in addition to Shideler. In the final, Castleman was never a factor, as Schule and Shideler fought it out, the former winning by about a two yards.
