In 1931, a 440yd running track was installed for the Amateur Athletic Association Championships, held there from 1932 to 1970. Besides the AAA championships, major athletics events, including international matches, were held at the stadium. In 1954 in a match against Russia Christopher Chataway broke the world 5000m record running against Vladimir Kuts. The one mile world record was broken there by Derek Ibbotson in 1957. In 1934 the second British Empire Games and the fourth Women's World Games were held at the venue. Also in 1931, Queens Park Rangers F.C. began the first of two spells playing at the stadium, until 1933 (the second spell was from 1962–63). QPR eventually decided against a permanent move to White City and stayed at Loftus Road. Between 1932 and 1958 the stadium hosted major British boxing events, with attendances peaking as high as 90,000 for the second meeting between Len Harvey and Jack Petersen in 1934. The first major fight at the stadium was Len Harvey’s unsuccessful challenge for the NBA Middleweight Championship versus Marcel Thil of France. Future heavyweight champion Primo Carnera suffered his only defeat on British soil here when he lost to Canadian Larry Gains in May 1932. Other important fighters to appear at White City include Jock McAvoy, Don Cockell, Nino Valdez, Henry Cooper and Terry Downes. In 1933, Wigan Highfield, a rugby league side, nearly became bankrupt. White City Company, owners of the stadium, decided to move the club to White City. Previously, only rugby union had been popular in southern England, professional rugby league being the preserve of northern towns and cities. Wigan Highfield became London Highfield with their debts paid. Their first try was scored by George "Porky" Davies, who went on to play for Liverpool Stanley and then St. Helens from 1938 to 1947. The White City Company lost money on the venture and decided not to continue with rugby league. London Highfield was the precursor to London Broncos, the current leading rugby league club in London. In 1966, Wembley's owner's refusal to cancel regular greyhound racing meant the match between Uruguay and France in the 1966 FIFA World Cup was played at White City. The game attracted 45,662 fans. The stadium was demolished in 1985 and the site is now occupied by BBC White City. White City Stadium was principally used for greyhound racing for the majority of its existence. The first greyhound meeting took place on 20 June 1927. The stadium became the Mecca of greyhound racing with tens of thousands of spectators attending meetings on a regular basis, particularly in the 1940s, and 1950s.
