Competitor bio:

Gloria has run over 25 marathons and is a member of The 7 Continents Marathon Club and Grand Slam Club, having completed marathons on all 7 continents and the North Pole. The 68-year-old took up running eleven years ago after being advised to perform weight-bearing exercises following a diagnosis of low bone density. She has since completed five of the six Marathon Majors - Berlin, Chicago, London, New York and Tokyo - as well as more unconventional races like the Antarctic Ice Marathon, Tenzing Hillary Everest Marathon, Great Wall of China Marathon and the North Pole Marathon. She has decided to challenge herself to run the continents again, this time in 7 days, and will use the opportunity to raise funds to help end human trafficking.
