ALTO HAZALLANAS, Spain (AP) American veteran Christopher Horner won the 10th stage of the Spanish Vuelta on Monday to claim the overall leader's jersey for a second time in this year's event.
The 41-year-old RadioShack-Leopard rider broke away on the steep, zigzagging special-category ascent up the Alto Hazallanas peak at the end of grueling 187-kilometer (116-mile) mountainous ride from Torredelcampo in southern Andalucia to win in 4 hours, 30 minutes, 22 seconds.
Vincenzo Nibali took off after Horner but was unable to catch the American, finishing 48 seconds behind in second. Spain's Alejandro Valverde led a small pack that came 1 minute, 2 seconds back.
"This race was a lot of work for me," Horner said. "When Nibali began to accelerate on the final climb I thought to myself it was the moment for me to attack and maybe win the race, which I did."
Horner also won the third stage of the Vuelta, with race organizers saying he became the oldest rider to earn a stage victory in one of cycling's three grand tours which also include the Tour de France and Giro d'Italia.
