The 2015 Boat Races took place on 11 April 2015. Held annually, The Boat Race is a side-by-side rowing race between male crews from the Universities of Oxford and Cambridge along a 4.2-mile (6.8 km) tidal stretch of the River Thames in south-west London. For the first time in the history of the event, the men's, women's and both reserves' races were all held on the Tideway; in the men's reserve race, Cambridge's Goldie faced Oxford's Isis after the women's race, as a preliminary to the main men's race, while the women's reserve race, held the day before, saw Oxford's Osiris race against Cambridge's Blondie.
