Beginning in 1973, the IAAF began hosting the renamed World Cross Country Championships each year. In 1975, the New Zealand men and United States women won, marking the first championships by non-European countries. In 1981 an African nation (Ethiopia) won the men's race for the first time, and a decade later an African nation (Kenya) won the women's race for the first time. Ethiopia or Kenya has captured every men's title since 1981 and every women's title since 2001. Through 2010, Kenya has won 40 World Cross Country Championships and Ethiopia has won 23.
