This is without a doubt one of the great stories I have ever heard. Paralympian Monique Von der Vorst won 2 silver medals in the handcycling road at the Beijing Paralympics and a World Ironman Championship. She has been paralyzed from the waist down since she was 13 as a result of a car accident.
From her website:
"(in 2010)Again I got involved in an accident, followed by a long period in the hospital. I got a lot spasm in my legs and suddenly I felt some twinklings in my paralyzed legs. It was so strange because I hadn’t felt anything in my left leg for 12 years. Later I could move my legs a bit and from that moment I really tried everything to get my legs working again. I spend months in the hospital and rehab centre, but now I am walking again after being in a wheelchair for almost 13 years!"
She has now signed on with the Robobank Women's Professional Cycling team with hopes to compete in the able bodies 2016 Olympics in Rio.
