The women's K-1 500 metres event was an individual kayaking event conducted as part of the Canoeing at the 1988 Summer Olympics program.
16 competitors entered in three heats on September 26, but one withdrew.
The heats served as placement rounds for the semifinals that were held two days later.
The top three finishers in each semifinal advanced to the final.
Schmidt, who won all three ICF Canoe Sprint World Championships women's kayaking events in 1981, 1982, 1983, 1985, and 1987, was an overwhelming favorite in this event but was upset by the fast-finishing Gesheva.
