This estate is named after racecourses and is first depicted on the 1967 OS map but is probably contemporary with the surrounding residential properties on the Cantley estate and dated to the late 1950s. Formerly the site had been home to a rifle range. Prior to this, the site was occupied by irregularly shaped fields indicative of piecemeal enclosure. The fields were marked as 'Micklehill Field' on the 1st edition OS map of 1854. Several pottery kilns were excavated from the surrounding area in advance of the construction of the housing estate and form an important regional group. Legibility of the former landscape is invisible.
