of the United States of America. Today, the 1852 trophy oars are the oldest intercollegiate athletic prize in North America. The race distance was increased to for the second rendition in 1855 and to the current in 1876. The Oxford–Cambridge Boat Race is the only longer side-by-side rowing event in the world, though slower stream makes the Yale–Harvard Race one to three minutes longer. Originally the race was just between the varsity crews but there are now three events: the 2-mile (3.2-km) freshman race, the 3-mile (4.8-km) junior varsity race, and the 4-mile (6.4-km) varsity race. The varsity crews compete for the Sexton Cup, the junior varsity for the F. Valentine Chappell Trophy, and the freshman for the New London Cup. The Hoyt C. Pease and Robert Chappell Jr. Trophies are awarded to the team that wins the majority of the three races. Typically the day before the freshman, junior varsity and varsity races, there is a two-mile (3.2 km) race between the spares for both crews. These "combination" boats are made up of second freshman boat and third varsity boat rowers (i.e. the "combi" or "combo" race). The winner of this race gets the James P. Snider Cup, as well as the right to paint its school's colors on the "rock" at Bartlett's Cove for the next day's races. Currently Harvard leads the varsity series at 95–55, the second varsity (JV) at 75–38, and the freshman series at 72–39–1. Yale holds the upstream course record with its time of 18:35.8 in 2015. The Crimson set the downstream—and Thames River course—mark of 18:22.4 in 1980. Trophies The Sexton Cup is presented to the winner of the varsity heavyweight race. The trophy is actually a combination of two former rowing trophies: The bottom is the original base of the Sexton Cup, with year-by-year results of race winners, while the upper portion retains the Yale and Harvard seals from the trophy which was awarded to the winner of the (now discontinued) graduate eights race. The F. Valentine Chappell Trophy is presented to the winner of the second varsity heavyweight race. Previously used for a discontinued event in this regatta, it was redesignated in 1983 to be awarded to the victor in the junior varsity contest. The New London Cup is presented to the winner of the freshman race. The city of New London donated this silver award in celebration of its bicentennial
