Japan's Teruyo Tanaka won T52 100m silver at the World Para-Athletics Championships - at the age of 60.
Tanaka, who first took up the sport in 1988, set a new season's best time of 22.85 seconds to finish second behind American Kerry Morgan, 45, in Dubai.
She won 800m gold at the Atlanta 1996 Paralympics and won further medals at the Sydney 2000 and Beijing 2008 Games.
"This medal means a lot, but now I want to find the next target to deepen my career," she told BBC Sport.
Asked how she feels competing against athletes younger, she replied: "I never want to be beaten by them."
The T52 classification is for wheelchair track athletes affected in both lower and upper limbs.
