Embarrassed officials at the World Championships said late Saturday that the women's marathon was 400 meters too short.
That means the time of winner Manuela Machado of Portugal - a personal best - will not count. She remains the winner, but all posted times in the race were declared invalid.Carl-Gustav Tollemar, the competition director, said the runners had run one lap short at the beginning of the race before they left the Ullevi stadium. They completed three instead of four laps in the stadium.
Machado, who turns 32 on Wednesday, was timed in 2 hours, 25 minutes, 39 seconds for the 26 miles, 385 yards, which would have been the second fastest time of the year.
Anuta Catuna of Romania was second, with Ornella Ferrera of Italy taking the bronze medal.
They will keep their medals, but their times, all personal bests and including Catuna's Romanian record, will be negated.
