The 156th Boat Race took place on 3 April 2010. Held annually, the event is a side-by-side rowing race between crews from the Universities of Oxford and Cambridge along the River Thames. The race was won by Cambridge. Of the eighteen competitors in the race, six were British. Of the non-British rowers, the Oxford crew featured the American Olympic finalists, the Winklevoss twins. It was the first time the race had a title sponsor; it was also known as the "Xchanging Boat Race", having been sponsored by Xchanging.
