I just came across an article in The Nation on world junior 800 champ Emmanuel Wanyonyi who ran 1:43.76 to win gold. It says he dropped out of school in Class 3 ( does anyone know how you are in Class 3?) to work as a herdsman for 7 years and that he was paid between $1.82 (200KS) and $9.09 (1000 KS) per month. Check this out.
The Nation wrote wrote:
At one time, he dropped out of Kapretwa Primary School while in Class Three and went to Kitale town in Trans Nzoia to work.
He took up a herdsman job for different families, where he earned between Sh200 and Sh1,000 a month.
“I worked to help my family which was suffering due to poverty. My parents could not pay school fees for the 12 of us,” narrated Wanyonyi, who said he continued running.
He stayed out of class for seven years before he was later spotted by primary teachers who enrolled him in Standard Seven where he started competing in various races, representing the institution up to the regional level in Kapsabet.
He also says he can run 1:40. "I can be able to run 1:40."
