Lolo Jones, the two-time Olympic hurdler, and pilot Jazmine Fenlator finished second in the World Cup women's bobsleigh season opener.
Canada's Kaillie Humphries and Chelsea Valois won the two-run competition at Lake Placid.
Jones, who aims to represent the United States at the 2016 Olympics, only took up the sport last month and could yet appear at the 2014 Winter Olympics.
Britain's Paula Walker and Gillian Cooke were sixth.
Another American duo with a track star, Elana Meyers and Tianna Madison, finished third.
Madison was part of the US world record women's 4x100 relay team at London 2012.
