At
Oxford University,
Eights Week constitutes the main intercollegiate rowing event of the year, and happens in May. Male and female
coxed eights[?] compete in separate divisions for their colleges. Some colleges have as many as three crews for each sex, and there are three divisions for each sex. The rowing events take place on the
Isis part of the
River Thames in the 5th week of Trinity term. Crews can progress up their division by bumping the boat in front. The aim is to become "head of the river" and stay in the lead position.
