Triathlon at the 2012 Summer Olympics

Women's Sunday was a suffragette march and rally held in London on 21 June 1908. Organised by Emmeline Pankhurst's Women's Social and Political Union (WSPU) to persuade the Liberal government to support votes for women, it is thought to have been the largest demonstration to be held until then in the country.Up to 500,000 women and men from all over the country attended the event, and 30,000 women marched to Hyde Park in seven processions and carried 700 banners, including one that read, "Not chivalry but justice".

The Kronenburgerpark is a park in the center of Nijmegen. It is close to the Central Railway Station and the Lange Hezelstraat. Where the park touches the Parkweg are the remains of the medieval walls with the Kruittoren (powder tower) (built around 1425).

The Great Pilgrimage of 1913 was a march in Britain by suffragists campaigning non-violently for women's suffrage, organised by the National Union of Women's Suffrage Societies (NUWSS). Women marched to London from all around England and Wales and 50,000 attended a rally in Hyde Park.

The London to Brighton Veteran Car Run is the world's longest-running motoring event, held on a course between London (51°30′31″N 00°09′49″W) and Brighton (50°49′42″N 00°08′22″W), England. To qualify, participating cars must have been built before 1905. It is also the world's largest gathering of veteran cars. The first edition, "The Emancipation Run" in 1896, celebrated the recently passed Locomotives on Highways Act 1896, which liberalised motor vehicle laws in the United Kingdom. The run has taken place most years since its initial revival in 1927. It currently takes place on the first Sunday in November, starting at sunrise, about 7:00 AM, in Hyde Park, London, and mostly following the old A23 road to the finish at Brighton – a distance of 54 mi (87 km). There are two official stops along the way: Crawley (for coffee) and Preston Park (in a suburb of Brighton). Preston Park is the official finishing point; the cars then proceed to Madeira Drive on the seafront, also the venue for Brighton's other big motoring event, the Brighton Speed Trials. The event is organised on behalf of the Royal Automobile Club, who emphasise that the event is not a race – they do not even publish the order in which cars finish, and participants are not permitted to exceed an average speed of 20 mph (32 km/h). Any that finish (many do not) before 4:30 PM are awarded a medal. There are a few other events preceding the Veteran Car Run, such as the Motoring Forum, the Veteran Car Run Sale, a motor show, and a participant reception.

Hyde Park is a Grade I-listed major park in Westminster, Greater London, the largest of the four Royal Parks that form a chain from the entrance to Kensington Palace through Kensington Gardens and Hyde Park, via Hyde Park Corner and Green Park past the main entrance to Buckingham Palace. The park is divided by the Serpentine and the Long Water lakes. The park was established by Henry VIII in 1536 when he took the land from Westminster Abbey and used it as a hunting ground. It opened to the public in 1637 and quickly became popular, particularly for May Day parades. Major improvements occurred in the early 18th century under the direction of Queen Caroline. Several duels took place in Hyde Park during this time, often involving members of the nobility. The Great Exhibition of 1851 was held in the park, for which The Crystal Palace, designed by Joseph Paxton, was erected. Free speech and demonstrations have been a key feature of Hyde Park since the 19th century. Speakers' Corner has been established as a point of free speech and debate since 1872, while the Chartists, the Reform League, the suffragettes, and the Stop the War Coalition have all held protests there. In the late 20th century, the park was known for holding large-scale free rock music concerts, featuring groups such as Pink Floyd, The Rolling Stones and Queen. Major events in the park have continued into the 21st century, such as Live 8 in 2005, and the annual Hyde Park Winter Wonderland from 2007.

Eia or Eye was an early Medieval manor in the parish of Westminster, Middlesex and is now a part of Central London. It was about one mile west of the Palace of Westminster/Whitehall, about 2 miles west-south-west of the walled City of London, and about half a mile north of the River Thames. Today, the area of the manor includes much of Hyde Park (which dates from 1536), the grounds of Buckingham Palace (1703), Belgravia, a country road known later as Park Lane and most parts of Mayfair, Pimlico, and Knightsbridge.

The 2011 anti-cuts protest in London, also known as the March for the Alternative, was a demonstration held in central London on 26 March 2011. Organised by the Trades Union Congress (TUC), it was a protest march against planned public spending cuts by the Conservative-Liberal Democrat coalition government that was formed in May 2010. Various sources estimated that the demonstration was attended by between 250,000 and 500,000 people. It was described as the largest protest in the United Kingdom since the 15 February 2003 anti-war protests and the largest union-organised rally in London since the Second World War.Demonstrators marched from the Thames Embankment, via the Houses of Parliament, to Hyde Park where a rally took place with speakers including the TUC general secretary Brendan Barber and leader of the opposition Ed Miliband, who addressed the assembled crowds.Several independent protesting groups, some of whom had moved from the main march, assembled further north in the heart of London's West End, where shops and banks were vandalised and some individuals clashed with police. Further clashes were reported later in Trafalgar Square. 201 people were arrested, and 66 were injured, including 31 police officers.

Tyburn Brook was a small tributary stream to the West Bourne or Westbourne and ran mainly in Hyde Park for a few hundred metres south by south-west. It has lost its catchment to natural drainage into the gravelly topsoil and to surface water, foul and in early Victorian style combined sewers (mixing both types of water) and its small collect, its source remains beneath the earth to feed into a mixture of these. The Serpentine, having been the Westbourne's main showing is now fed by three boreholes instead. It is not to be confused with the much longer Tyburn, Ty Bourne or River Tyburn, but frequently was confused until the early 19th century as both were well west of the walls of the City of London.

The City of Westminster is a city and borough in Inner London. It is the site of the United Kingdom's Houses of Parliament and much of the British government. It occupies a large area of central Greater London, including most of the West End. Many London landmarks are within the borough, including Buckingham Palace, Westminster Abbey, Whitehall, Westminster Cathedral, 10 Downing Street, and Trafalgar Square. Westminster became a city in 1540, and historically, it was a part of the ceremonial county of Middlesex. Its southern boundary is the River Thames. To the City of Westminster's east is the City of London and to its west is the Royal Borough of Kensington and Chelsea. To its north is the London Borough of Camden. The borough is divided into a number of localities including the ancient political district of Westminster; the shopping areas around Oxford Street, Regent Street, Piccadilly and Bond Street; and the night-time entertainment district of Soho. Much of the borough is residential, and in 2019 it was estimated to have a population of 261,000. Despite large swaths of parks and open spaces, including Hyde Park and most of Regent's Park, the population density of the district is high. The London Westminster borough was created with the 1965 establishment of Greater London. Upon the creation, it inherited the city status previously held by the then Metropolitan Borough of Westminster from 1900, which was first awarded to Westminster in 1540. The local government body is Westminster City Council, and there has been a Lord Mayor of the City of Westminster since 1966, while the area is also within authority of the Mayor of London, an office created in 2000.

Radio 2 Live (formally known as Radio 2 Live in Hyde Park and Radio 2's Festival in a Day) is a British music festival that took place from 2011 to 2019 in Hyde Park in London, and is due to be held in Leeds in September 2022. The idea behind the event was for music fans who enjoy live music but are not comfortable with the idea of a full multi-day festival to be able to experience the variety of artists and the atmosphere that such a festival would offer, without the associated necessities such as camping. The festival is designed to appeal to the over 35 demographic that makes up the majority of BBC Radio 2 listeners, although the event attracts fans of all ages. The line-up is compiled of the various adult contemporary music and specialist genres featured on Radio 2, including folk, country, soul, rock and jazz. The festival was hosted by Chris Evans and later Jo Whiley alongside other Radio 2 presenters and is broadcast live on the station and streamed on the BBC Red Button. In 2022, the corporation announced that the festival will be moving away from London, with the 2022 festival set to be held over two days at Temple Newsam Park in Leeds, but it was cancelled following the death of Queen Elizabeth II.In 2017, the attendance was 45,000.

Ossulstone is an obsolete subdivision (hundred) covering 26.4% of – and the most metropolitan part – of the historic county of Middlesex, England. It surrounded but did not include the City of London and the area has been entirely absorbed by the growth of London. It now corresponds to the seven London Boroughs of Inner London north of the Thames and, from Outer London, in decreasing order, certain historic parishes of the London boroughs of Ealing, Brent, Barnet, and Haringey.

Queen live in Hyde Park 1976 was a concert by the band Queen. The concert took place on 18 September 1976 in Hyde Park, London. It was part of a brief summer tour of the UK by the band; they also played in Edinburgh and Cardiff on this tour. The Hyde Park gig was a free concert, which drew in a crowd of over 150,000, which was one of the largest audiences for any concert in London. The free concert was organised by Richard Branson, an entrepreneur at the time.There is more than one audio source of this concert as well as a video. According to Roger Taylor, the drummer of Queen, the complete show was supposed to be shown on TV in early 1977 but was never aired. Since then, the full show has leaked out to the Internet, though in terrible quality. Over the years, some of the footage has been shown in various documentaries and there are rumors of a future official release. The 2011 reissue of A Day at the Races includes a performance of "You Take My Breath Away" from this date. The rest of the day's music was provided by The Kiki Dee Band, Supercharge, The Rich Kids (not to be confused with Midge Ure's band of the same name), Broken Wreck Chords and Steve Hillage. Elton John did not appear duetting with Kiki Dee for "Don't Go Breaking My Heart". She sang to a 2/3 life-sized cardboard cut-out of Elton instead.A post-concert review by Record Mirror linked the performance, and especially Brian May's appearance and style, to the death of Jimi Hendrix, exactly six years earlier on 18 September 1970, but stating that "Queen aren't Hendrix,...they're Freddie Mercury."The concert was shot on videotape, then kinescoped onto 16 mm film. Reportedly, the film negatives have been damaged. However, snippets from a high quality videotape source appeared on the A Night at the Opera 30th Anniversary DVD.
