The Championship Course, Rowing venue on the River Thames in London, United Kingdom

The Championship Course is a rowing venue on the River Thames between Putney and Mortlake in southwest London, stretching approximately 6.8 kilometers. The course is defined by granite stones including the Putney Stone at the start and the University Stone at the finish, with bridges like Hammersmith serving as reference points for crews.

The course was established in 1845 as the venue for the first official Boat Race between Oxford and Cambridge to avoid disturbances from large ships in other parts of the river. During World Wars I and II and the recent pandemic, races were canceled, but the course remained central to British rowing history.

The name refers to its role as the venue for the famous Boat Race between Oxford and Cambridge, making this stretch the center of British rowing tradition. The banks are lined with rowing clubs where athletes and spectators gather to witness and participate in a sporting heritage that connects to the universities and local communities.

The best time for races is during the incoming tide, approximately one and a half hours before high water, as this helps boats move faster. Spectators can watch from the banks or boats, especially during the Boat Race in March or April when the area becomes particularly busy.

A rare detail is Chiswick Eyot, a small uninhabited island in the Thames that becomes visible at low tide and affects water flow during races. The start is marked by a large granite stone that has served as an orientation point for over 180 years.
