While he was not able to answer every attack made by the elite general classification riders, he did answer the majority of them and as a result he surpassed all expectations earning a top 10 finish coming in almost three minutes behind Wilco Kelderman who finished seventh, and nearly ten minutes ahead of Marc Soler who finished 9th.
