Born and raised in Park City, Utah, Rosie Brennan is a three-time Olympian, having competed in the 2018, 2022 and 2026 Olympic Winter Games, and throughout multiple World Cup seasons, was ranked in the top 10. Rosie announced her retirement from World Cup ski racing in late April of 2026. 

Rosie is one of the strongest and most dominant athletes on the World Cup circuit. After over a decade on the National Team, she has over 300 World Cup starts, 12 podiums, and two victories, most recently landing on the podium in the Drammen City Sprint in Drammen, Norway. Even though she only started skiing at 14, her later-than-typical start never hindered her from finding success on the world stage. 

Rosie has represented the USA at three Olympic Winter Games with her best result earning her a fourth-place finish in the sprint. She was the first American to hold the overall World Cup leader's bib, World Cup sprint leader's bib and the World Cup distance leader's bib all at the same time - showing her versatility in distances and techniques. 

Outside of racing, Rosie is very involved academically. This upcoming summer, Rosie will begin her Master's of Sports Nutrition at Liverpool John Moores University. Rosie holds a Master's of Education and an undergraduate degree from Dartmouth University.
