The Championship Course is a stretch of the River Thames between Mortlake and Putney in London, England. It is a well-established course for rowing races, particularly the Oxford and Cambridge Boat Race. The course is on the tidal reaches of the river often referred to as the Tideway. Due to the iconic shape of the Championship Course, in orthopaedic surgery, an S-shaped incision along the crease of the elbow is commonly referred to as "a boat-race incision resembling the River Thames from Putney to Mortlake."[1]
