The 73rd Boat Race took place on 30 March 1921. 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. Cambridge, with the heavier crew, went into the race as reigning champions, having won the previous year's race. In total, nine of the participants in this year's race had previous Boat Race experience, and five had won a silver medal in the 1920 Summer Olympics. In this year's race, umpired by former rower Frederick I. Pitman, Cambridge won by one length in a time of 19 minutes 45 seconds. It was Cambridge's third consecutive win, the fastest winning time since 1913 and the narrowest margin of victory since 1913. The result took the overall record to 39–33 in Oxford's favour.
Background
is a side-by-side rowing competition between the University of Oxford and the University of Cambridge. The race was first held in 1829, and since 1845 has taken place on the Championship Course on the River Thames in southwest London. The rivalry is a major point of honour between the two universities and followed throughout the United Kingdom and worldwide. Cambridge went into the race as reigning champions, having won the 1920 race by four lengths; Oxford led overall with 39 victories to Cambridge's 32. Oxford were coached by H. R. Baker, G. C. Bourne who had rowed for the university in the 1882 and 1883 races, C. D. Burnell and R. P. P. Rowe who had rowed four times between 1889 and 1892. Cambridge's coaches were John Houghton Gibbon, who had rowed for the Light Blues in the 1899 and 1900 races, Sidney Swann and G. E. Tower. For the thirteenth year the umpire was old Etonian Frederick I. Pitman who rowed for Cambridge in the 1884, 1885 and 1886 races.
Crews
The Cambridge crew weighed an average of 12 st 11.75 lb, per rower more than their opponents. Oxford's crew contained five participants with Boat Race experience, while Cambridge saw four of the 1920 crew return. Five of the participants were silver medallists in the men's eight at the 1920 Summer Olympics: Oxford's Sebastian Earl, Walter James, Richard Lucas and Guy Oliver Nickalls, and Cambridge's John Campbell. Two rowers were registered as non-British, Oxford's Francis Bacon Lothrop was American while Cambridge's Campbell hailed from Australia.
Race
Oxford won the toss and elected to start from the Surrey station, handing the Middlesex side of the river to Cambridge. Pitman, the umpire, started the race on a "moderate tide" in good conditions at 5:00 p.m. Cambridge made the quicker start, outrating Oxford and holding a half-length lead by the time the crews reached Craven Steps. Gaining further, the Light Blues were a quarter of a length clear of the Dark Blues by the Mile Post. At this point, the Cambridge boat attempted to cross into the Surrey side of the river, but Oxford responded and surged to become level by the time the crews passed below Hammersmith Bridge. As the course of the river now favoured Oxford, they pulled away and, according to author and former Dark Blue rower George Drinkwater, after a "ding-dong struggle" held a half-length lead by Barnes Bridge. Oxford were forced to allow the Light Blue space; the Cambridge stroke P. H. G. H-S. Hartley took advantage and spurted to push the Dark Blues off their line. The bend in the river now favouring Cambridge, they levelled proceedings and pushed on to win by one length in a time of 19 minutes 45 seconds. It was their third consecutive victory, the fastest winning time since the 1911 race and the narrowest winning margin since the 1913 race. It took the overall record in the event to 39-33 in Oxford's favour.
