The Claremont Colleges' 5C Ultimate Frisbee team, the Braineaters, was founded in 1979 at Pitzer College with the team name stemming from a 1950's B-movie title. Made up primarily of Pitzer students, the Brains played their first games against teams such as Oxy and Redlands. Founded on the principals of good spirit and fair play, the early teams were led by people such as Jeff Landesman and Howie Wein. Throughout the 80's the team expanded across the 5 colleges, steadily bringing in more and more Pomona and Harvey Mudd students. The late 80's and early 90's saw the Brains establish themselves as the strongest small school Ultimate team in SoCal.
In 2006, the Braineaters had a breakout season, following surprising success at the Trouble in Vegas tournament. They went on to finish fourth at regionals, losing in the "gametogo" to nationals against UCSB. With only 1 bid in 2007, the Brains finished a respectable 3rd at regionals, and after winning their section in 2008, saw dissapointing losses to Arizona and UCSB at regionals to again finish 4th.
With the establishment of DIII College Ultimate, Claremont became one of the premier programs in the Division. In 2011, the Braineaters won their first ever national title behind the strong cutting of Callahan nominee Tommy Li and others. The Braineaters cemented their names in the more personable division by hosting DIII Warmup in February and appearing at nationals every year since its inception.
