At the age of nine, Jamie's family feared he would never walk again. Twenty years later, he set off to run 5,000 miles coast to coast across Canada. When Jamie decides to repay the hospitals that saved his life as a child, he embarks on the biggest challenge of his life: running the equivalent of 200 marathons back-to-back, solo and unsupported, in –40 degree weather, surviving all kinds of injuries and traumas on the road, and wearing through 13 pairs of trainers. And he does it all dressed as the superhero, the Flash. Though his journey was both mentally and physically exhausting, it was the astounding acts of kindness and hospitality he encountered along the way that kept him going. Jamie soon came to realize that every person who helped him towards his goal was a superhero, too.
