Parade to salute London 2012 heroes Olympic and Paralympic heroes will be celebrated at the end of a sparkling summer of British sport. Last night the curtain came down on the Paralympic Games in a stunning closing ceremony. And today the celebrations spill out onto the streets of the capital as tens of thousands are expected to turn out to watch The Greatest Team Parade. 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. During its 20-minute journey, it will pass over the Olympic Park at 3.40pm before reaching The Mall a minute later. London mayor Boris Johnson said: "This summer our great city has hosted an unbelievable spectacle of sport and thousands will want to celebrate the achievements of our athletes by coming to the parade. It promises to be an incredible afternoon but I do want to remind people coming that we expect the route to be extremely busy and planning ahead is absolutely crucial if they are going to be able to make the most of their day. The parade will include more than 90% of Britain's medal winners. Organisers have warned there will be extensive road closures around the route of the parade, which starts from Mansion House in the City at 1.30pm. Members of the public will be able to watch the parade as it travels along Queen Victoria Street and Cannon Street, passing St Paul's Cathedral, continuing along Fleet Street, past Aldwych and into The Strand, before reaching Trafalgar Square. A big screen at the base of Nelson's Column, with live commentary, will allow spectators to cheer on the athletes as the parade makes its way past Trafalgar Square, a Greater London Authority (GLA) spokesman said. From Trafalgar Square, the athletes will go through Admiralty Arch into The Mall, travelling down to the Queen Victoria Memorial. Most roads along the route will close at 11am, with those around Guildhall and Gresham Street in the City set to shut at 6am. An area from Admiralty Arch to the Queen Victoria Memorial will be ticket-only and reserved for groups who had made "an invaluable contribution to the Games and the success of our athletes," the GLA said. This will include 14,000 volunteers, members of the blue light services, military personnel, Team GB and ParalympicsGB coaches and support staff, friends and family of the athletes and schoolchildren from every London borough. Farah, who won gold medals in both the 5,000 and 10,000m, said he had had the "perfect" Olympics. Appearing on ITV's Daybreak, he said: "I could never have imagined it would be like that. As an athlete you dream of becoming an Olympic champion, but not in front of a home crowd, and also twice doing it. He said he was "very excited" about today's parade. He added: "It should be good. There's a lot of people out there, you know Chris Hoy and the rest of the guys, Bradley Wiggins. I'm looking forward to it, mixing with everyone and having a good laugh. It's time for us to enjoy it one last time, I guess. Farah also spoke about getting children involved in sport from a young age. He said: "It's very important that we introduce children to sport. Sport's helped me. I've travelled around the world. If I didn't get into sport at an early age then I wouldn't be here today. Speaking ahead of taking part in the parade, diving bronze medallist Tom Daley said he expected London 2012 to be an inspiration to many. He told BBC News: "The range of different sports that we've competed in, the sports that aren't normally getting recognition have done really well at these Olympic Games. It's given people news ideas of new things to try. He added that it would be "tough" going back into training following the excitement of the Games. He said: "That is the toughest part of any four-year cycle, is actually starting it off again. Because you come off that high of being at the Olympic Games and competing at what you've worked for for the last four years, and then you have your time off and then you go back to training, and going back to training is the hardest thing. You know that you've got another four years of the hardest training that you can think of. You've got to go through all those ups and downs, the tears, the tantrums and all that kind of stuff leading into the Games. Daley spoke alongside Pendleton, who told BBC News she planned to stay involved in sport despite retiring after the Games. She said: "I'm just so looking forward to being a spectator. What I've done in my career and where it's finished, it's the right time for me. Asked who she thought would win BBC Sports Personality of the Year, she said: "I think it's going to be one of the hardest decisions those judges have ever had to make, to narrow it down to only 10 athletes to get through into the final group. It's not just about BBC Sports Personality, there'll be athletes winning left, right and centre, which I think is wonderful. I think things can only get better for sport in the UK.
