Frenchman Damien Gaudin, riding for Europcar, won Sunday's Paris-Nice prologue, a 2.9km time trial around Houilles west of Paris. Gaudin, a three-time French national pursuit champion, bagged the yellow jersey after seeing off compatriot Sylvain Chavanel by 0.56sec and Dutchman Lieuwe Westra as the 26-year-old garnered his first career win five years after turning professional. Monday's first stage proper is a 195km ride from Saint-Germain-en-Laye to Nemours.
