Check out this great article on training with the Kenyans posted on GreatRun.org.
Key points to Kenyan living
*Start runs very slowly but accelerate until at the end you are running very, very hard.
*Run sessions very, very hard.
*Follow runs with a full range of stretching, drills, sit ups and medicine ball work.
*Watch TV at all times between training except when eating or reading.
*Take a nap if there is nothing on TV.
*Eat ugali as much as possible. Does your sweat carry the feint smell of maize? If not eat more ugali.
*When you walk, walk slowly. Very slowly.
*Run only on grass or tracks. Walk to the park rather than running there. Remember to walk slowly.
*Make your tea using milk instead of water and add sugar in the kind of quantity you would normally add milk.
*Do not train in the rain unless absolutely necessary.
"Rest. That is the secret no-one knows. No-one realises how much rest they get. It is why Kenyans train so hard."
