Crew
Columbia's Rowing team was founded in 1873. The program consists of three distinct teams today, Men's Heavyweight, Men's Lightweight (founded in 1922), and Women's Rowing (founded in 1986).
In 1878 the "Columbia College Boat Club" became the first non-English team to win a race at the Henley Royal Regatta. The team last won a US national championship in 1929.
Currently, they practice on the Harlem River. Why they moved their boathouse from the Hudson, nobody knows.
