Diggins, Schumacher make US cross-country skiing history with World Cup double

• US men and women win World Cup races same day

• Schumacher and Diggins sweep new 5km event

• Tour de Ski milestone for American cross-country

American cross-country skiing reached a milestone on Wednesday when, for the first time, an American man and an American woman won World Cup races on the same day.

Gus Schumacher and Jessie Diggins delivered the historic double at stage three of the Tour de Ski in Toblach, Italy, both prevailing in a newly introduced 5km heat mass start free event that rewarded speed, pacing and collective tactics rather than head-to-head positioning.
