World championships in Nordic skiing, short track speed skating and Alpine snowboarding highlight winter sports competition on NBC Sports, Olympic Channel and Peacock Premium this week.
Jessie Diggins takes aim at cross-country medals on Tuesday in her best individual event, the 10km freestyle, and in Thursday’s relay in Oberstdorf, Germany.
Diggins, who in 2018 teamed with since-retired Kikkan Randall to win the U.S.’ first Olympic cross-country skiing title, can become the first American to win an individual world title. The U.S. has never earned an Olympic or world medal of any color in a men’s or women’s relay.
