Olympic champions Mo Farah, Jessica Ennis and Sir Chris Hoy will be among 700 British athletes taking part in Monday's victory parade to mark their incredible achievements at London 2012.
Sunday night's stunning Paralympics closing ceremony will bring the curtain down on an incredible summer of sport. The event will be followed by Britain's Olympians and Paralympians travelling through the capital to celebrate the huge medal hauls of both teams.
Thousands are expected to line the streets of London to celebrate the country's Olympic and Paralympic achievements one last time.
Team GB finished third in the medal table with 29 golds, 17 silvers and 19 bronzes while the Paralympic team also finished third with 120 medals, easily surpassing a pre-Games target of 103 medals.
The Greatest Team Parade will see athletes travel on 21 open-top floats, grouped in alphabetical order by their sport. The stars of the Olympics' "Super Saturday" will be on the first three floats.
The first will include Farah, the Olympic 5,000 and 10,000m winner, followed by heptathlon gold medallist Ennis, with long jump champion Greg Rutherford in the third float.
Team GB's cycling stars Sir Chris Hoy, Jason Kenny, Laura Trott and Victoria Pendleton will be in float seven, followed by double equestrian gold-medal winner Charlotte Dujardin, rowing champion Katherine Grainger, Ben Ainslie, Britain's most successful Olympic sailor, and triathlon gold medallist Alistair Brownlee.
Paralympians Hannah Cockcroft, Jody Cundy, Sophie Christiansen and Jonnie Peacock will be given little time to recover from the closing ceremony to take part in the parade.
British Airways will lead a flypast with the Red Arrows during the event after receiving special permission to fly over The Mall.
The flame-coloured Firefly A319 aircraft, which was used to bring the Olympic Flame to the UK at the start of the Games, will display a special "thank you" message on its underbelly. During its 20-minute journey, it will pass over the Olympic Park at 3.40pm before reaching The Mall a minute later.
