This mean that in 14 editions, Kenya won 9 Gold medals, 7 silver and 3 bronze, followed by Australia (2 gold and 2 bronze), UK (1 gold, 2 silver and 2 bronze, sweeping the podium in the only year without Kenyan Team...), South Africa (1 gold, 2 silver and 2 bronze), Botswana (1 gold), Jamaica (2 silver), Canada (1 silver and 1 bronze), Trinidad (1 silver), Zimbabwe and New Zealand with 1 bronze.
The situation of the UK athletes (that can always put in the championships athletes from 4 different Countries : Engalnd, Scotland, Wales and Ulster) doesn't seem the one of one Country that can dominate the World having more talent than everybody else. In the past, there was already somebody speaking about the Arian Supremacy, and I remember didn't finish very well.
