Mary Keitany of Kenya aged 35 won her third London Marathon on Sunday, while fellow Kenyan Daniel Wanjiru, won the men’s race in 2:05:56. It’s no real surprise that the Kenyans once again dominated. For the last 15 years, the male winners have all come from East Africa (12 from Kenya, 3 from Ethiopia). The East African woman have been just as dominant too, in the last 8 years all the winners have been born in Kenya or Ethiopia.
The dominance of African nations, particularly Kenya, in distance-running events is one of the most fascinating topics in exercise performance physiology.
