The CRASH-B Sprints World Indoor Rowing Championships was the world championship for indoor rowing, raced over a distance of 2,000m. The regatta is sponsored by Concept2, and raced on their C2 rowers. Originally held in Harvard's Newell Boathouse, the regatta moved in turn to the Malkin Athletic Center, the Radcliff Quadrangle Athletic Center, MIT's Rockwell Cage, Harvard's Indoor Track Facility, the Reggie Lewis Track and Athletic Center, Boston University's Agganis Arena, and in 2019, to the Boston University Track and Tennis Center. The regatta is held in late February each year.
