The event is a key part of National Paralympic Day, an annual event designed to tap into the success of London 2012. 

Cockcroft won two gold medals at those Paralympic Games, in the T34 100 metres and 200m. 

"Being here on the start line in the Stadium has brought back some amazing memories of when I won my gold medals," said 22-year-old Cockcroft, an ambassador for BT. 

"I remember that moment like it was yesterday and can still hear the crowds cheering me on. It was a very special moment.

“It is wonderful that Para-athletics can be celebrated in such a way, at the home of the London 2012 Games.

"So many dreams have been created here, including mine - so it’s fitting that this year Para-sport can be celebrated in style."

Jonnie Peacock, who beat South Africa's Oscar Pistorius to win the T44 100m at London 2012, has also urged the public to throw its support behind National Paralympic Day.

Besides the athletics, the public can also secure their seats to cheer on some of Britain's brightest talent in Para-Swimming, as athletes including Paralympic champions Ellie Simmonds, Ollie Hynd and Jessica-Jane Applegate take on the rest of the world in an event at the Aquatics Centre on the Queen Elizabeth Olympic Park. 

Free activities are also open for all to enjoy, including the chance to meet Paralympic medallists Sophie Christiansen, Natasha Baker and Will Bayley amongst others, plus the chance to try out a whole range of sports.

There will also be  performances from the Mayor of London’s Liberty Festival, which will showcase the best of British talent as it presents another exciting line-up of deaf and disabled artists, musicians and performers.

“I can’t wait to be back at Queen Elizabeth Olympic Park to celebrate National Paralympic Day 2015," said Peacock, who is also due to take part in the IPC Athletics Grand Prix final.

It’s a great family day out, and I’m thrilled that Athletics is joining swimming on the competition programme this year.

"People should definitely get their tickets to ensure the home crowd make plenty of noise and give their athletes the home advantage.

“I’ve been a keen supporter of National Paralympic Day in previous years and there’s so much on offer for fans to enjoy.

"I’d encourage people to come along to Queen Elizabeth Olympic Park to join us in celebrating the Paralympics, whether that be through watching the sport, meeting some of their favourite athletes or just having a go at some of the sports on offer.

“This is our day to celebrate the Paralympics, and it’s going to be an unmissable event.”
