Dutch rider Pieter Weening won the first stage competitively raced after Weylandt's death, and took over the race leadership for four days. He surrendered it to another stage winner, strong overall favorite Alberto Contador who dominated the field on the way up Mount Etna. Although it was perhaps against his will, Contador continued to hold the race leadership through the end of the first half of the race, topping the overall standings with the much more difficult second half of the Giro still to race.
