Organisers called off the super-G in Courchevel, France, due to heavy overnight snowfall and fog making the slope unsafe to race on. A super-G on Saturday was also cancelled.
They said the races would not be replaced, leaving Odermatt 158 points clear of Austrian Vincent Kriechmayr with one race to come in Norway on March 22nd and 100 points for a win.
Odermatt is also in the running for the giant slalom title, leading Norwegian-born Brazilian Lucas Pinheiro Braathen by 48 points with one race to go.
The Swiss has won the overall World Cup for the fifth season in a row and the downhill for the third consecutive year.
