The event will take place in Trafalgar Square on 8 September 2011 – a day ahead of the Paralympic Games ticket launch – and will allow the public to experience first-hand the inspiration and excitement that the Paralympic Games will bring to the UK next year.
Highlights of the day will include the chance to see Paralympic gold medallist and BT Ambassador Oscar Pistorius in action, and a Sitting Volleyball Guinness World Record attempt.
There will be demonstrations of a wide range of sports, including Wheelchair Basketball and Wheelchair Rugby, while ParalympicsGB stars such as Ellie Simmonds and Sascha Kindred will also take part in the celebrations.
The day will also see the International Paralympic Committee extend an invitation to athletes and National Paralympic Committees around the world to participate in the London 2012 Paralympic Games.
Tickets for the London 2012 Paralympic Games will go on sale the following day, with applications open from 9 to 26 September 2011. Approximately two million tickets will go on sale, with more than one million people having already registered their interest online.
Seb Coe, Chair of LOCOG, said: 'We've got a fantastic line-up of Paralympic activity due to take place in early September and hosting International Paralympic Day in Trafalgar Square is a great way to kick things off.
'It will be an exciting day and a great way for the UK public to find out about each of the 20 sports at the Paralympic Games and to get a chance to meet some of the world’s top Paralympic athletes. I would urge everyone to get involved and register their interest in Paralympic tickets before they go on sale from 9 September.'
In further Paralympic activity, Sainsbury's will be hosting Sainsbury's Super Saturday on Clapham Common on 10 September. The day will feature demonstrations of Paralympic sport as well as live music from top British acts such as Pixie Lott and The Saturdays.
