The route suits me because it is hilly but not excessively so. I hope to repeat my success from two years ago, so I rode the Tour of Trentino in order to arrive in the best possible condition and got into a long breakaway on Thursday."Carlos Quintero of Team Colombia said: "We have a mixed team with Edwin Avila and Sebastian Molano for the sprints and for the mountains, Edward Dias, Alex Cano and me. The idea is to do a very good race. It's time I took responsibility and accepted the challenge of riding for the General Classification."Tomasz Marczynski of Torku Şekerspor said: "I'm in good shape. Two weeks ago I won three stages and the General Classification at the Tour of Morocco. I felt very, very good there. I've ridden the race twice with CCC, in 2010, when I fell, and last year, when I was 13th, riding in the service of Davide Rebellin. This year, I'm riding for myself. I've based the whole of the first part of my season around this race. For my team, Torku, it is the equivalent of the Tour de France. And for all the teams, it is a fantastic opportunity to show themselves on Eurosport for eight days."
