“This is a huge logistical operation, and we are thrilled that the final pieces of the jigsaw are falling into place,” said Anita Gerhardter, the CEO of Wings for Life Foundation.
“It’s an extremely exciting and proud moment for us all, and we are so looking forward to our big day. So many people, not least the athletes, have put so much effort into this, and we are really hoping for a fabulous day of inspiring action from all of our venues."
