Although most of the athletes had uneventful participations, weightlifterMabel Mosquera won the bronze medal for Colombia, while cyclistMaría Luisa Calle originally finished in the bronze medal position, but was later disqualified under the strict liability rule after she tested positive for Heptaminol, a prohibited stimulant. However this proved to be a false positive due to isometheptene presence in an analgesic prescribed during the competition. The bronze medal was returned to Calle on November 23, 2005.
