In 2012, Claire Lomas became the first person to complete the London Marathon in a bionic suit. She had been paralysed from the chest down in a horse riding accident just five years before.
Now, the 36-year-old from Leicestershire is set to make history again.
On Wednesday, Lomas will start the Great North Run in another robotic suit, hoping to complete three miles a day before crossing the line on Sunday.
Lomas, a former event rider, broke her neck, back and ribs when she was thrown from her horse during the Osberton Horse Trials in 2007.
She told the BBC: “Training has been challenging so I am actually just ready to give it a go now.”
Lomas wrote in a blog: “My accident was an eventing accident. Horses take up your life. I’d just got to the highest level in the sport about eight months before and it was such a big loss for me.
“But as much as I loved it, it stopped me doing other things so since then life has opened new doors for me. I always wanted to do the Great North Run because it looks amazing, with a brilliant atmosphere.”
Lomas, who is raising money for the Nicholls Spinal Injury Foundation, will be dropping in on school assemblies along the 13.1 mile route.
