Heras optimistic

Roberto Heras, defending champion and three-time Vuelta a España's winner, will start on Saturday in Granada determined to defend his number one dossard for another year. "I feel optimistic and with a changed 'chip', because the Vuelta is a different race. It's very different to one month ago," said the Liberty Seguros captain after training with his teammates on Thursday.

Heras had a poor Tour de France, finishing 45th overall a 1:38:33 behind the winner Lance Armstrong. But he has regained his strength in the last month and is prepared for his home race. "In training I felt very good and because of that I am optimistic," he said. "I have been the whole month in Béjar, where there is a good enough area to know how you are, because it is very hard. I have worked climbing long mountains, doing motorpacing and all my sensations are very positive."
