As Simon Kindleysides, 34, took his first step in the London Marathon in April, he felt as if magic was in the air.

"As we were walking toward the first mile, we actually started joining all the runners," he said. "Everyone was on the streets, cheering, and that was a magical moment." As time went on, the crowds and other racers spread around. Kindleysides and his team of eight supporters continued walking.

Kindleysides, who is paralyzed(瘫痪的)from the waist down and typically uses a wheelchair, was equipped with an exoskeleton(体外骨骼)to help him walk. His supporters walked with him to change the batteries in his exoskeleton so he could keep moving.

In 2013, Kindleysides was diagnosed with a brain tumor (肿瘤) that was growing in a way that pressed on certain nerves, leading to him losing feeling in his legs. He was told he would never walk again. Before his paralysis, the London-based singer and dancer had "always wanted to run a marathon," he said, but he never made the plan to do so--until this year.

During the London Marathon, the last two miles were the hardest. "At that point, I was exhausted. It was freezing cold, and I was hurting emotionally," Kindleysides said. But he kept going. "I didn't want to let people down. I had a team of eight, and I was raising money for The Brain Tumour Charity," he said. "I didn't want to let them down, myself down, and I thought if I would get this far, I would have to continue."So he continued and made history as the first paralyzed man to complete the London Marathon on foot.

Then, recovering at home, he shared his accomplishment with his three children. "They used to say I'm the only dad in their whole school who's in a wheelchair, and now they say I'm their dad, the only one who has walked a marathon," he said.
