The Great Subscription Purses were a series of flat horse races in Great Britain run at York Racecourse, usually over a distance of 4 miles, that took place each year in August from 1751 to 1833.
On the Friday of the meeting a race was run for four-year-olds, each carrying 9 stone.
[1] The format was changed in 1759, with a race for horses aged six and over being added on the Thursday.
From 1759 onwards all three races were run over four miles in a single heat.
In the four-year-old race the weights stayed the same and in the four- and five-year-old race four-year-olds carried 8 st 3 lb and five-year-olds 8 st 10 lb.
