The Lightweight Boat Races

The Lightweight Boat Races are a series of annual rowing races between men's and women's lightweight crews representing the University of Oxford and the University of Cambridge.
The first men's race took place in 1975, being joined by the women's race in 1984. Both races are currently held on the Championship Course from Putney to Mortlake, although they previously formed part of the Henley Boat Races, along with various other rowing races between the two universities, including the openweight women's Boat Race. Members of both teams are traditionally known as blues or half blues and each boat as a Blue Boat. Competitors at the events have gone on to compete at international and Olympic levels.

History

Richard Bates, a Cambridge undergraduate, organised a Boat Race between lightweight men's crews of Oxford and Cambridge universities in 1975, to take place at Henley-on-Thames. The race was joined by the openweight women's Boat Race two years later, thus forming the Henley Boat Races. The first lightweight women's boat race took place at the event in 1984. Reserve races have taken place since 2000 for the lightweight men and in some years since 2012 for the lightweight women.
In 2019, the lightweight men's race moved to the Championship Course from Putney to Mortlake, where it has been held since. The lightweight women's race made the same move the following year in 2020.
For the men's race the average weight of the crew must not exceed, with no rower weighing over. For the women's race, no rower can exceed.
The races receive annual press coverage, and competitors from both Universities have gone on to compete at international and Olympic levels.
