The 2026 777 CHALLENGE
"Ordinary people can do extraordinary things."
Bobby White ran the 2026 World Marathon Challenge® in memory of his brother Anton · As covered by BBC News.
Two decades after losing his 15-year-old brother, the dad-of-two from Clydebank self-funded the seven-continent challenge and crossed all seven finish lines, averaging 5:09:58 a marathon, raising more than £32,000 for the Glasgow Children's Hospital Charity that supported his family. It's the kind of story this event produces every January: ordinary people carrying something bigger than themselves across seven continents in a week.
