May 12, 2003 – Aussie sprinter Robbie McEwen (Lotto-Domo) finally got his stage win, after being relegated in Stage 2. A clean sprint saw McEwen take the stage over current pink jersey wearer Alessandro Petacchi (Fassa Bortolo). The big news of the day was World Champ Mario Cipollini ( Domina Vacanze-Elitron) finishing 100th, once again not being in the final gallop to the line. Petacchi leads, but with the excellent climbers and time trialists Stefano Garzelli ( Vini Caldirola-SO.DI) Francesco Casagrande (Lampre) one can only wonder for how much longer..
