Chris Horner (RadioShack-Leopard) attacked on the sharp climb at the end of stage three of the Vuelta a Espana on Monday to take a surprise win and put himself into the overall race lead.
Horner - the oldest rider in the race at 41 - waited patiently among the group of favourites near the front and put in a perfectly-executed move on the final climb to Mirador de Lobeira to jump clear.
Alejandro Valverde (Movistar) chased hard after Horner on the category three climb, but could only manage second with Joaquim Rodriguez (Katusha) claiming third.
Horner now takes to the top of the general classification thanks to his winner's time bonus, eight seconds ahead of overnight leader Vincenzo Nibali (Astana). Stage two winner Nicolas Roche (Saxo-Tinkoff) in third at 14 seconds.
The stage was far from straightforward, with brisk winds splitting the bunch on several occasions and a large crash wiping out a swathe of the peloton.
Bauke Mollema (Belkin) was one of those caught in a major crash and had to chase furiously get get back in touch with the bunch as Katusha and Movistar wound up the pace. Mollema managed to regain contact with the peloton before the final climb, and all credit to him for having the energy to place sixth on the line.
The day's early break of Cyril Bessy (Cofidis), Luca Dodi (Lampre-Merida), Fabricio Ferrari (Caja Rural), Vicente Reynes (Lotto-Belisol) and Pablo Urtasun (Euskaltel-Euskadi) was caught inside the final 40km.
Juan Antion Flecha (Vacansoleil-DCM) as the first rider to put in a serious atack on teh final climb, but he was soon caught and passed by Italian champion Ivan Santaromita (BMC Racing), who managed to hold on until the final kilometre before fading with his effort.
Horner cruised past Santaromita, followed by a group of contenders, but the American was not going to be caught. As well as taking the stage and race lead, Horner's effort netted him a mention in the history books - as the oldest Grand Tour stage winner in history.
On Tuesday, the riders travel from Lalin to Finisterra over 189km with another uphill kick at the finish line.
