My school was six miles away from where I lived on the farm. I had to walk and run, there and back every day, through gorges and over rivers. If I was late, there was a very big stick waiting for me.
In the rainy season, sometimes to get to the first lesson we had to run really quick, because we had to cross the river to school and we'd have to go up and down the bank to find a place to cross because there is no bridge.
I used to run to school, 10k every day. And this at altitude, perfect preparation, really.
