Australian Rohan Dennis wins opening Tour de France stage Rohan Dennis won the first stage of the Tour de France in record speed in the individual time trial Saturday, and defending Tour champion Vincenzo Nibali gained precious time on his rivals. Dennis powered along the 8.6-mile flat and windy urban circuit through cycling-mad Utrecht, Netherlands, in 14 minutes, 56 seconds. “There’s still emotions going on,” said a thrilled Dennis, who previously held the world hour record when covering a distance of 32.6 miles in February. Nibali, who tried to counter the searing heat (97 degrees) by warming up with ice cubes strapped to his back, finished 43 seconds behind Dennis in 22nd place. Asafa Powell, filling injured Usain Bolt’s shoes for Jamaica, ran the third-fastest 100 meters of the year at the Diamond League meeting in Paris. In the women’s 100, Jamaica world and Olympic champion Shelly-Ann Fraser-Pryce’s 10.74 seconds made her the fastest woman this year.
