What a summer it has been.

In the last few months we have enjoyed twists and turns, triumph and heartache, constant drama and so many stories of triumph against adversity.

But now it's all over and all we have left are memories and one last day of celebration.

Britain's many sporting heroes will be saluted today as a huge precession snakes its way through the streets of London.

Starting at 1.30pm athletes will 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 Mo Farah, the Olympic 5,000 and 10,000m winner, followed by heptathlon gold medallist Jessica 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 also 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.
