List of British flat horse races

A list of notable flat horse races which take place annually in Great Britain, under the authority of the British Horseracing Authority (BHA), including all conditions races which currently hold Group 1, 2 or 3 status in the European Pattern.

Races
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 feature in the British Champions Series.

Races are run on the Rowley Mile at Newmarket unless 'Newmarket (July)' is written, in which the July Course is used.

Handicaps
Criteria for inclusion;
 * Class 2 or Class 3 races worth £75,000 or more and which are not consolation races for runners eliminated from other handicaps (Races marked as H are heritage handicaps, which are always Class 2).
