 His biggest result was winning the Under-23 section of the Grand Prix des Nations, after which Le Télégramme reported that Wegelius was one of the most promising riders of his generation.Wegelius' cycling aspirations suffered an early setback, after being injured in an accident involving an all-terrain vehicle, which resulted in his spleen being removed and the news that he would never cycle again.He recovered, however, and had his first professional break in 1999, when he rode as a stagiaire for the ill-fated Linda McCartney Racing Team.
