Royal Ascot: Chesham Stakes
| The Chesham Stakes, the opening race on the final day of the Royal meeting,  is a Listed race over 7 furlongs for two-year-olds named after the 3rd  Baron Chesham who served as Master of the Buckhounds in 1900-01. It was  established in 1919, and it was originally contested over 5 furlongs, replacing  the first leg of the Triennial Stakes which was first staged in 1848 when won  by Elthiron. The race has an unusual restriction, being open only to horses sired  by stallions who won over ten furlongs or more.   For a time the Chesham Stakes was contested over 6 furlongs, but was  extended to 7 furlongs in 1996. |
