The earliest written record of the word “Kenya” was noted by Johann Ludwig Krapf. Chief Kivoi told him it was called “Kï-Nyaa” or “Kïïma Kïïnyaa” possibly because the black rock and the white snow reminded the various tribes of the feathers of the cock ostrich, the biggest bird in the World. They can grow up to 2.7 meters tall and weigh up to 145 kilograms. It is the fastest biped on the planet, and can run at speeds of 70 kilometres/hour, covering 5 meters in a single stride. Since 1988, 21 Kenyan males and 13 females have won the Boston Marathon, more than any other nation in each case.
