Kenyan javelin thrower Julius Yego won gold at the World Championships in Beijing in 2015, with a new African record throw of 92.72 meters. His win puts him in the position to become the first Kenyan to win an Olympic gold medal in a field event this month in Rio. Yego's rise to fame is a bit more unconventional than the standard javelin medalist. He claims to be self-taught and relies on YouTube videos to perfect his technique. While Yego's hometown in the Rift Valley has produced several Olympic sprinters, there's a shortage of javelin specialists, so he had to learn on his own. He specifically found inspiration in Andreas Thorkildsen, a Norwegian javelin thrower who competed in the 2004 and 2008 Olympics. Yego watched videos of Thorkildsen throwing while taking notes on his technique and training methods.
