 A gold or silver medallist outside of these two competitors seemed unlikely; Bahamian Chris Brown, Irishman David Gillick, Frenchman Leslie Djhone and the other two runners from the United States (Gil Roberts and Lionel Larry) were seen to be capable of a bronze at best.On the first day, Ramon Miller surprised as the fastest qualifier in the heats, scoring a new personal best of 45 seconds.Tabarie Henry, Djhone and Renny Quow were the next fastest, and African record holder Gary Kikaya was most high-profile casualty of the first round, having been disqualified for a lane infraction.
