In 2002 he finished fifth in Paris–Roubaix, a result he would duplicate in 2005. In the 2006 Paris–Roubaix he was once again in the group of favourites, but he helped teammate Fabian Cancellara win the race and finished 19th himself. In his last race, the 2007 Paris–Roubaix, he finished 11th after a strong race, where only a mechanical failure prevented him from following the favorites. Again a teammate, Stuart O'Grady, won the race. Michaelsen rode at four Olympic Games.
