Career
He is best known for his victories in the Italian semi-classic Tre Valli Varesine in 2012 and winning a stage of the 2013 Critérium du Dauphiné. He broke away in the final 30 kilometers with Anthony Delaplace from the Saur–Sojasun squad. The pair cooperated well together to resist to the peloton"s charge and Veilleux beat Delaplace to the sprint, while the bunch reached the finish line only 5 seconds after them.
In the spring of 2012, Veilleux was part of a long breakaway in the monument Paris-Roubaix which was composed of about a dozen units.
They broke away at kilometer 70 and were joined (scattered) well after the Forest of Arenberg, some 110 kilometres (68 mi) later. Leading to the Tour de France, it was announced that Veilleux was under consideration to participate in the race, but in the end he was not chosen, which drew considerable press coverage in his country.
In August 2012, Veilleux met success on the Mi-Août Bretonne, which is classified as a 2.2 race by the UCI. Veilleux was part of a ten men escape group, and dropped them with 17 kilometres (11 mi) to go, winning solo. He held on to the leader"s jersey until the fourth stage time trial.
Shortly after the Dauphiné, Veilleux was confirmed by Team Europcar as a participant for the Tour de France, therefore becoming the first Québec-born rider in history to participate in the event.
On 11 September 2013, he announced his retirement from professional cycling, saying he wanted to continue his studies in mechanical engineering at Laval University and to start a family.
