In his first World Curling Championship in 1998, Ulsrud skipped Norway to fifth place. After serving as the alternate for Pål Trulsen's team in 1999, he returned again as skip in 2006–2009, making the playoffs for the first time in 2006 and then defeated USA's Team Pete Fenson to win the bronze medal. Two more bronze medals followed in 2008 and 2009.
