Nike OTC Marathon

The Nike OTC Marathon (sometimes styled "Nike/Oregon Track Club Marathon") was a marathon held annually from 1973–1984 in Eugene, Oregon. It was organized by the Oregon Track Club (OTC) and sponsored by Nike.

The women's world record for the marathon was set at the Nike OTC Marathon by Jacqueline Hansen, who ran 2:38:19 in 1975.

The American women's marathon record was broken four times at the Nike OTC Marathon in the 1970s and 1980s, by Jacqueline Hansen (2:38:19 in 1975), Kim Merritt (2:37:57 in 1977), Julie Brown (2:36:23 in 1978), and Joan Benoit (2:26:11 in 1982). No other marathon has been the venue for more than three American women's marathon records.
