[1] After great success with their first track at Belle Vue in Manchester in 1926, they opened both White City and Harringay stadiums in 1927.

The driving force behind the GRA, and its managing director until the 1960s, was Brigadier-General Alfred Critchley, who wrote in his autobiography that, when he first learned of greyhound racing, "It immediately occurred to me that this might prove to be the poor man's racecourse".

[3] The opening night was on Tuesday 13 September 1927 and drew in a crowd of 35,000, and the racing was dampened by persistent rain all evening.

The opening race was the Chorley Wood Stakes, and it was won by Baltard Castle over 500 yards in a time of 30.80 sec at 3–1 for trainer Sid Jennings.

The original trainers were Kennedy, Jennings, William Spoor, Harry Buck and Reginald Grey.

The pups under nine months were reared under the supervision of William Skerratt on farms in and around Blythe Bridge near Stoke-on-Trent before graduating to Northaw.

[6] Bendeemer trained by Jack Kennedy finished fourth in the 1928 English Greyhound Derby final before the Mick the Miller appeared at Harringay for the only time in 1929.

[7] The track was the first to race a steeplechase in 1934, which featured a hurdle, a water jump, a collapsible dummy brick wall and a brushwood hedge.

[7] With the advent of war, major competitions were badly hit, with many postponed until 1945; the 1940 Greyhound Derby was affected after White City cancelled the event despite the fact that it had already started on 15 June.

[11] In late 1968 the stadium underwent a facelift with new stands, a new track surface with improved banking, and new distances of 450, 725, and 900 yards.

[12] In 1987 the GRA was taken over by Wembley plc, and with the 23-acre site of the stadium valued at £1 million per acre the sale plans accelerated.

The cheetahs ran in public for the first time to a packed house at the Romford track, on Saturday, 11 December 1937.

[27] The huge postwar popularity of speedway declined through the early 1950s and Harringay was one of many tracks that discontinued their involvement in the sport in that period.

In 1950, with a gap to fill in their schedule, the promoters of the speedway staged an unofficial "Australian Championship" with the top Australian riders competing in Britain at the time (the field included Ronnie Moore, who although born in Australia, grew up in New Zealand and raced as a New Zealander).

Other riders in the meeting included Aub Lawson, Jack Young, Vic Duggan, Bill Longley, Lionel Levy, Graham Warren and Bob Leverenz.

Graham Warren won the "Australian Championship" from Aub Lawson and future dual World Champion Jack Young.

There were a range of occasional events including the Hollywood Motor Rodeo in May 1955 [29] and local school sports days from the early 1950s until 1964.

[30] Eight years later a crowd attending a greyhound racing event ran riot after a second-placed dog was disqualified.

They started bonfires which they fed with pieces of the hare trap...smashed electric lamps and arc lights, tore down telephone wires, and broke windows, wrecked the inside of the judge's box, overturned the starting trap...They also attacked the tote offices...[31]In June 1957 another disqualification provoked a further riot at a greyhound racing event.

Similar levels of disorder as the previous riot were dealt with on this occasion by firemen from six fire appliances who turned their hoses on the crowd.

In line with its property disinvestment strategy, the GRA sold the Harringay site in 1985 to Sainsbury's for £10.5 million.
