I believe you'll develop speed via strength work which includes hill running either repeats or running hilly courses as the Kenyans do on a steady basis.
I was born to a Nigerian dad and a Kenyan mom and coming to the States was really academic.
To the Kenyan families school doesn't really matter because none of them are going on to college. Almost all of drop out of school and so they're spending their time learning things that are important to them.
It's a matter of life and death for this country. The Kenyan forests are facing extinction and it is a man-made problem.
