Kenya vs. Ethiopia

In baseball, you have the Giants vs. Dodgers, the Yankees vs. the Red Sox, the Cardinals vs. the Cubs and many other bitter rivals. In basketball, it used to be the Celtics vs. the Lakers (ah the greatness that was the 80s basketball). In football, you have the Patriots vs. every other team trying to knock off the wanna be Niners :D. In distance running, there is only one true rivalry and that is Kenya vs. Ethiopia. In this documentary I found on my friend and yours, youtube.com, here is a historic look at this great rivalry. When you list the top runners in the history of distance running, many come from these two countries and that list includes Abebe Bikila, Kip Keino, Mamo Walde, Miruts Yifter, Henry Rono, Paul Tergat, Haïlé Gebresélassié, and the most dominant current runner, Kenenisa Bekele.
