Fauja Singh, a British-Indian man believed to be the world's oldest marathon runner, has died in a road accident at the age of 114. Singh, a global icon who was once featured in an Adidas advertising campaign, began running when he was 89 years old. He ran nine full marathons between 2000 and 2013, when he retired.
