The Henley Boat Races were a series of annual rowing races between various crews representing the University of Oxford and the University of Cambridge. The event included the Lightweight Men's Boat Race from 1975 to 2018, the Women's Boat Race from 1977 to 2014, the Lightweight Women's Boat Race from 1984 to 2019 and the Collegiate Boat Races from 2010 to 2019. Between 2015 and 2020, the openweight and lightweight Varsity races previously held at Henley were relocated to the Championship Course to match the openweight men's Boat Race, at which point the Collegiate Boat Races were scrapped. History Henley Boat Races took place annually in late March or early April the week before the University Boat Races, which are held on the Championship Course on the Thames in London. The Henley Boat Races began as men's lightweight races in 1975 and enlarged to incorporate the Women's Boat Race and their reserve crew race from 1977 and the women's lightweight race from 1984. In 2000, the lightweight men added a race for their reserve crews, Nephthys (Oxford) and Granta (Cambridge). The races took place in 2001, at the Holme Pierrepont National Watersports Centre in Nottingham. The lightweight men's race fell into abeyance after 2009 as a result of Cambridge not fielding a Granta crew from 2007, giving Oxford a row over for three years. From 2016, Nephthys and Granta raced again, sometimes on a different date or location to the main Henley Boat Races. A women's lightweight reserve race was held in 2012 prior to race day and took place from 2016 on race day. The 2013 event was moved to Dorney Lake as a result of flooding on the Thames. In 2015, the Women's Boat Race moved further down the River Thames to the Tideway to take place as a combined men's and women's Boat Race. The event was moved to Dorney Lake again in 2018 due to "adverse river conditions on the Thames at Henley" and the collegiate races were cancelled. The Lightweight Men's Boat Race made the same move to the Tideway in 2019, followed by the Lightweight Women's Boat Race in 2020, although the Lightweight Boat Races continue to operate separately to their openweight counterparts. The races received annual press coverage, and competitors from both Universities have gone on to compete at international and Olympic levels.
