University Boat Race Stones

From Wikipedia, the free encyclopedia

The University Boat Race Stones are two small stone markers on the southern bank of the River Thames in west London, one just downstream of Chiswick Bridge and the other just upstream of Putney Bridge.

The stones define the start and finish points of the Championship Course used in the Oxford and Cambridge Boat Race and other rowing races, including the Head of the River Race. The stones are marked "U.B.R" for University Boat Race.
