Kaillie Humphries is off to a strong start in the Olympic debut of women’s monobob in Beijing.

The reigning world monobob champion, Humphries finished two runs on Sunday in a time of 2:09.10. The American currently holds a massive 1.04-second lead over second-place finisher Christine de Bruin of Canada, who completed her runs in 2:10.14.

Germany’s Laura Nolte came in third with a time of 2:10.32. Three-time Olympic medalist Elana Meyers Taylor of Team USA finished fourth in 2:10.42. She sits nearly a half-second ahead of fifth-place sledder Huai Mingming of China.

In the first Olympics for women’s monobob, a one-woman bobsled event, Humphries is also competing as an American citizen for the first time. Born and raised in Canada, Humphries gained U.S. citizenship in December.

The medal runs are scheduled to take place Monday in Beijing.
