Twelve kilometers into proceedings, a 13-strong group got away, and like the stage that preceded it, the break established a medium-sized lead around the four and a half minute mark after 70km - perhaps considered to be a controllable advantage by the Rabobank-led peloton. In the move were: Guillame Bonnafond (AG2r), Giampaolo Cheula and Christopher Froome (Barloworld), Vasili Kiryienka (Caisse d'Epargne), Philip Deignan and Simon Gerrans (Cervelo), Giovanni Visconti and Andriy Grivko (ISD), Francesco Gavazzi (Lampre), Francesco Reda (Quick Step), Rubens Bertaglioti (Diquigiovanni), Evgeny Petrov (Katusha), Martin Müller (Milram) and Eduard Vorganov (Xacobeo).
As the riders passed under the sandstone arch of Pontecchio Marconi with 2.7km left to race, ISD's Andriy Grivko took flight just before the start of the climb to San Luca, a further 600 metres ahead.
The Ukrainian got the head start he wanted, but with the first 500 metres averaging a lung-busting 13.6%, Barloworld's Christopher Froome took over, setting an even faster tempo as the road became less steep.
But in the next half-kilometre, beginning with a short 16% pitch, the road kicked up again to average 12.2%. It must've hurt like hell.
As the final 600 metres began to level out (unbeknown to him, Froome and Grivko had effectively blown), Gerrans pushed home his advantage, now a certain winner.
