Kaillie Humphries won gold on Sunday in the first-ever women’s monobob event at the Olympics. United States teammate Elana Meyers Taylor earned silver, becoming the oldest American woman to medal at the Winter Olympics at 37 years old.

As a result, Humphries and Meyers Taylor became the first women to medal in bobsled at four straight Olympics.

Meyers Taylor, who was in fourth place after her first two runs, made up time during her third and fourth runs to finish in 4:20.81, just ahead of bronze medalist Christine de Bruin of Canada.

Humphries dominated the field, winning by a margin of 1.54 seconds, the largest in Olympic bobsledding in 42 years. She also became the first American to win gold for two countries — USA and Canada — at the Winter Olympics. Humphries, a three-time Olympic medalist and five-time world champion, became an American citizen last December and began competing for Team USA after accusing Canadian bobsled coach Todd Hays of mental and verbal abuse.

Humphries and Meyers Taylor will now pair up for the two-woman bobsled event, which begins Friday.
