A 3-Year-Old Boy
Budhia Singh became a huge celebrity in India when he started running long distances at an extremely young age. He was born into poverty in India and reportedly sold to a traveling salesman at age 2, eventually landing up in an orphanage. According to Runner’s World, he had run 48 “marathons” – unorganized races of marathon length – by age five. Sadly, Singh was shot and killed in 2008.
