The 2015 Boat Races took place on 11 April 2015. Held annually, The Boat Race is a side-by-side rowing race between 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.
Oxford's women won the first running of the Women's Boat Race on the Tideway, and the 70th overall, by six and a half lengths, to take the overall record in the event to 41–29 in Cambridge's favour. Oxford also won the men's reserve race, with Isis winning by three lengths. In the main men's race, umpired by the six-time Blue Boris Rankov, Oxford won by six and a half lengths in a time of 17 minutes 34 seconds, taking the overall record in the event to 81–79 in Cambridge's favour. The women's reserve race was won by Oxford's Osiris by fifteen lengths, making the overall record 21–20 in Cambridge's favour.
