In 2007, Humphries was placed low on the Canadian depth chart and did not feature at the 2006 Winter Olympics. In an effort to compete she considered representing the United Kingdom, the country of her then-fiancé, Dan Humphries. Opting to remain with the Canadian team, she gained a spot on the roster after signing up for a bobsleigh driving school. She won the silver medal in the mixed bobsleigh-skeleton team event at the 2008 FIBT World Championships in Altenberg, Germany.
