Keough missed the 1992 season due to injury. In 1993, she returned, and spent most of the year concentrating on the 800 metres. She finished second to Kelly Holmes at both the UK Championships and AAAs Championships. She achieved her best, with 2:01.82 at the Cologne Grand Prix. At the World Championships in Stuttgart, she was a late replacement for Phylis Smith in the individual 400 metres and reached the semi-finals. Then in the 4 × 400 m relay, she won a bronze medal, along with Smith, Tracy Goddard and Sally Gunnell.
