The River Thames is one of the main rowing areas in England, with activity taking place on the Tideway and on the 45 separate lock reaches on the non-tidal section. The river hosts two major rowing events, The Boat Race and Henley Royal Regatta, and many other regattas and long distance events take place on the river. Dorney Lake in Buckinghamshire was opened specifically as a rowing lake besides the Thames, and has become the venue for a few events that formerly took place on the river. Other lakes adjacent to the Thames are the Redgrave Pinsent Rowing Lake and Royal Albert Dock. Rowing, or sculling, includes skiffing, dinghy racing and cutter racing in which the boats are also propelled by blades.
Rowing Regattas generally take place during the summer months and usually consist of short side-by-side sprint events, with heats and finals.
"General" refers to a mix of skiffing, cutters, dinghies and other rowed craft.
Rowing and Long Distance events generally take place in the winter months and are usually processional races with competitors being set off at time intervals and judged on the basis of comparative timing or by bumping (catching up the boat in front). Many of the long distance events on the Tideway are raced over The Championship Course and apart from the Boat Race and Wingfield Sculls may begin from Mortlake or Putney depending on river conditions.
Rowing on the river is generally organised through clubs based on the Thames, which include the following.
