York drains a bog and builds a racecourse.

Flooded out at Clifton Ings, York levelled and drained the marshy Knavesmire into a horseshoe-shaped course; the first meeting ran in 1731.
York had raced by the Ouse at Clifton Ings, a course with one persistent flaw: it kept ending up underwater. In 1730 the city moved racing to the Knavesmire, a marshy stretch of common land south of the walls whose name, mire and all, says plenty about the ground the contractors faced. Levelling and draining took a considerable effort, and the horseshoe-shaped course opened for its first meeting in 1731. York has raced on the same common ever since.
