Astana riders Alexandre Vinokourov and his most valuable domestique Andrei Kashechkin have decided to call it a day for this season after the Züri-Metzgete, the pair announced. Even though the two could not participate in the 2006 Tour de France, they made the Vuelta a España a tough battle for Alejandro Valverde, and managed to turn the race around in the final week, to take home the maillot oro.
It is this achievement that French trainer Frédéric Grappe questions now in Vélo Magazine, saying that the physical progress Vinokourov achieved since the Tour de France last year was practically impossible. "He would have gained, in one year, between 35 and 40 watts on the verge of the anaerobic threshold? That's nearly impossible on that level of training. Even the best training in the world would not lead to this kind of performance increase," Grappe told the French magazine, speaking of those last two mountain stages where the Kazakhstani reversed the overall classification.
"This remarkably fast performance imrpovement in the mountains needs to be explained precisely as to the methodology (of training) used. Moreover, this sudden explosion of potential in the mountains comes late - at the age of 33. Something's not right there," he continued.
