The 70th Boat Race took place on 13 March 1913. Held annually, the Boat Race is a side-by-side rowing race between crews from the Universities of Oxford and Cambridge along the River Thames. Oxford went into the race as reigning champions, having won the previous year's race. The two crews contained a total of five medallists from the 1912 Summer Olympics. Umpired by former Cambridge rower Frederick I. Pitman, Oxford won this year's race by three-quarters of a length in a time of 20 minutes 53 seconds. The victory took the overall record in the event to 39–30 in their favour.
