The distances of the races are expressed in
miles,
furlongs and
yards. In 2017 the BHA concluded a racecourse survey and remeasurement which led to some racecourses changing the exact distance of some races, or moving race start points to fit with advertised race distances. The distances in the table below are exact distances. Race distances are often given to the nearest furlong: e.g.
The Derby's exact distance is 1 mile 4 furlongs and 6 yards, but it is called a 1 mile 4 furlong race. The races in
bold are run on an all-weather surface. Races are run on the Rowley Mile at
Newmarket unless 'Newmarket (July)' is written, in which the July Course is used. ==Group 1==
