"That is a conversation that we are starting, we'll see how far we get, but I can assure you that already they are in listening mode," she said.

He said: "Your limitations are as far as you allow them to be: it's not about the medal but being able to do something I never thought I'd be able to."He added: "My whole thing is just whatever you're going through, believe in yourself and rely on yourself because ultimately you've only got yourself."

During Sunday's race, the 42-year-old will be supported by his brother and a physiotherapist he met during his first three months of treatment.He uses elbow crutches and has splints on each leg to remain balanced but can't feel as much on the left side of his body.The south-east Londoner plans to walk at the start and end of the race and along the Embankment and Tower Bridge. He will use a wheelchair for the rest of the route.

"It's been daunting because I haven't been in wheelchair for 10 or 11 years so going back to learn how to use a wheelchair has been hard," he said."I'll be so happy to cross that line – it's about raising awareness for the next person.

"I want people to think: a guy who defied all the odds did it and they can do it and turn up for themselves."

He revealed his son, who was aged just two at the time he was shot, was his "biggest motivation" to recover.The team studied the trackways in detail during the dig. As well as making casts of the tracks, they took more than 20,000 photographs to create 3D models of both the complete site and individual footprints.

"The really lovely thing about a dinosaur footprint, particularly if you have a trackway, is that it is a snapshot in the life of the animal," Prof Butler explained."You can learn things about how that animal moved. You can learn exactly what the environment that it was living in was like. So tracks give us a whole different set of information that you can't get from the bone fossil record."

One area of the site even reveals where the paths of a sauropod and megalosaurus once crossed.The prints are so beautifully preserved that the team have been able to work out which animal passed through first - they believe it was the sauropod, because the front edge of its large, round footprint is slightly squashed down by the three-toed megalosaurus walking on top of it.
