On which racecourse in England is the Rowley Mile?

Newmarket Racecourse, which has a capacity of 45,000, is a British Thoroughbred horse racing venue in the town of Newmarket, Suffolk.

There are two courses - the Rowley Mile Course and the July Course. Both are wide, galloping tracks used for Flat racing only (no fences).

The Rowley Mile Course has a 1 mile 2 furlong (2 km) straight with minor undulations towards 'The Bushes', two furlongs (400 m) out. The penultimate furlong (200 m) is downhill and the last is uphill, forming 'The Dip'. Races beyond the distance of 1m 2f start on the 'Cesarewitch' or 'Beacon' course which turns right-handed into the straight.

The July Course, also sometimes called the Summer Course, has a 1 mile (1600 m) straight, known as 'The Bunbury Mile'. After 2 furlongs (400 m), there is a long downhill stretch before the uphill furlong (200 m) to the finish. This course also uses the 'Cesarewitch/Beacon' course for longer distances, again turning right into the straight.

The Rowley Mile is used for racing in the Spring and Autumn, while the July Course is used in Summer. The Rowley Mile has a grass strip used by light aircraft, and formerly by the Royal Air Force (RAF) as RAF Newmarket.
