100 metres Breaststroke, Women

Date	24 July 1980
Status	Olympic
Location	Plavatelny basseyn, Sportivny kompleks Olimpiysky, Moskva
Participants	25 from 19 countries

East German Ute Geweniger had broken the world record at a meet in Magdeburg in May 1980. In the heats in Moscow she bettered that record with 1:10.11. She could not reproduce that in the final, coming hom in 1:10.22, but that was third fastest time ever, and won her the gold medal. She started slowly, and was only fifth at the turn, but cruised home for the victory. Geweniger would win this event at the 1981 and 1983 European Championships and the 1982 World Championships. At the 1981 and 1983 Europeans, she won nine gold medals in all events, with four individual golds in Split in 1981. Denmark’s Susanne Nielsson won bronze in Moscow, as she had done at the 1978 Worlds. With the Americans in Moscow, Geweniger would likely still have won, but Tracy Caulkins would have been a formidable opponent for her.
