Formula 1 is arguably the pinnacle of motorsports - even getting a license to drive at that level places you among the elite, and a couple of CART championship titles don't do anything to diminish your stature. Alex Zanardi may not have been the absolute best driver, but then again he drove during the start of the Schumacher era, when everyone was in eclipse.
He ended his driving career in one of the last major crashes of the modern open wheel era, where he lost both legs. Once he had recovered, he discovered a new release for his need for speed and competition, and took up handcycling. He has been even more successful in this new area than ever before, and this week he added a new gold medal at the Paralympic competition in Rio to the ones he has already from London in 2012, and his eight gold medals in world championship competition since 2011.
It's hard to find a better example of determination than Alex Zanardi.
