ADELAIDE - Australian cyclist Bridie O'Donnell broke the world hour distance record for women Friday, eclipsing the previous one by more than 600 metres. Cycling Australia confirmed on Twitter that O'Donnell had "set a new #UCIHourRecord of 46.882km" for the gruelling velodrome event. "I can't believe I broke a world record," the 41-year-old said after getting off her bike and hoisting it above her head at the Super-Drome in Adelaide. The previous record for distance ridden in 60 minutes by a woman was 46.274 kilometres set by American Molly Shaffer Van Houweling in Mexico in September. O'Donnell said she had been nervous the day before the event, but had felt a lot more "calm and ready" as she prepared to race. She kept to her plans for pacing herself for the sprint against the clock.
