The stretch of the River Thames between Mortlake and Putney in London, England is a well-established course for rowing races, particularly the Oxford and Cambridge Boat Race. It is often referred to as The Championship Course. 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."
In 1845, it was agreed to stage the Boat Race (which had on five previous occasions been rowed from Westminster Bridge to Putney) on a course from 'Putney Bridge to Mortlake Church tower'. The aim was to reduce the interference from heavy river traffic.
The course was later defined by two stones on the southern bank of the river, marked "U.B.R." for University Boat Race: one just downstream of Chiswick Bridge, close to The Ship public house, and the other just upstream of Putney Bridge. The course distance is 4 miles and 374 yards (6,779 m), as measured along the centre of the river's stream.
Since the Boat Race moved to this course in 1845, it has always been raced on a flood tide from Putney to Mortlake except in 1846, 1856 and 1863. The Wingfield Sculls is also raced from Putney to Mortlake. Most other events race on an ebb tide from Mortlake to Putney.
In April 1869, the Harvard University Boat Club challenged the Oxford University Boat Club to an "International University Boat-Race" of coxed fours on the Boat Race course. The race took place on 27 August 1869 and was narrowly won by Oxford. The new Atlantic cable allowed daily reports to be received by all major newspapers across America within 23 minutes of the finish. U.S. public interest in the event was huge, with more publicity than any sporting event to date, and within two years of the event the "newly awakened interest in rowing at many of the most noted seats of learning" doubled the number of boat clubs in the US, and led to the formation of the Rowing Association of American Colleges.
