Athletes are Born, Not Trained

According to the common wisdom, Sunday's LaSalle Bank Chicago Marathon
is wide open in the absence of three-time champion Khalid Khannouchi.
Well, sort of.
The favorites are Paul Tergat, Moses Tanui and Ondoro Osoro, all of Kenya,
and one Japanese runner, Takayuki Inubushi. In other words, it's wide
open to East and North Africans and a handful of elite marathoners from
Asia and a few other countries. But don't bet the house on any Americans
finishing among the elite.
In fact, here's a prediction that may startle: An American-born runner
may never win another Chicago Marathon. The sobering reality is that American-born
runners, white and black, almost never win major marathons anymore--or
any elite distance races, for that matter.
What has befallen the great American distance-running tradition, built
on the exploits of Jim Ryun, Joan Benoit Samuelson, Frank Shorter and
The world distance rankings paint a dismal picture for Americans. East
Africans hold nine of the top 10 spots in the men's rankings. That includes
The trend in the women's division is much the same: The world's top two
road runners, Kenyans Catherine Ndereba and Lornah Kiplagat, are the favorites
in Chicago. Overall, Kenyans hold seven of the top 10 spots in the women's
So-called experts will offer the usual clichés: Americans are soft.
They can't match the grueling training regimens of African runners.
Earlier this year, there was some talk of an American "comeback" after
18-year-old phenom Alan Webb broke Ryun's 1,500-meter scholastic record.
Don't believe it. Webb offers potential, but even if he should emerge
as an elite runner, he will be one compared with hundreds from East and
The American "resurgence" rests almost entirely on the shoulders of two
African runners who have emigrated to the U.S.: Moroccan-born Khannouchi
and Meb Keflezgihi, a native Eritrean who shattered the U.S. 10,000-meter
record in May.
Note that Khannouchi is from mountainous sections of North Africa and
Keflezgihi is from East Africa, the ancestral home of the world's top
distance runners. Runners from highlands that snake along the western
edge of the Great Rift Valley that cuts through Ethiopia, Kenya and Tanzania
have clocked more than 60 percent of the best times ever run in distance
races. Kenyans alone win 40 percent of top international events. The Nandi
district of 500,000 people--1/12,000th of the Earth's population--boasts
an unfathomable 20 percent, marking the greatest concentration of raw
athletic talent in sports history.
What's going on? Science certainly does not support the popular notion
that Kenyans prevail because they train harder or run to school, myths
peddled by the media.
"I lived right next door to school," Kenyan-born Wilson Kipketer, world
800-meter record-holder, says with a laugh. "I walked, nice and slow."
For every terrific Kenyan miler there are others, like Kipketer, who get
along on fewer than 30 miles a week. "Training regimens are as varied
in Kenya as anywhere in the world," notes Colm O'Connell, coach at St.
Patrick's, the famous private school that turned out Kipketer and several
other Kenyan greats.
The explanation for this phenomenon, it turns out, is in the genes. Why
are African-Americans such poor distance runners? Highly inheritable characteristics
such as skeletal structure, muscle-fiber types, reflex capabilities, metabolic
efficiency and lung capacity are not evenly distributed among populations
and cannot be explained by known environmental factors. Though individual
success is about opportunity and "fire in the belly," thousands of years
of evolution have left a distinct footprint on the world's athletic map.
"Very many in sports physiology would like to believe that it is training,
the environment, what you eat that plays the most important role," says
Bengt Saltin, director of the Copenhagen Muscle Research Center, who outlined
his findings in Scientific American magazine.
"But we argue based on the data that it is in your genes, whether or not
you are talented or whether you will become talented. The extent of the
environment can always be discussed, but it's less than 20 or 25 percent."
Is this a racial issue?
"Absolutely not," Saltin says. This is not an issue of black and white,
but the consequence of thousands of years of evolution in varying terrains.
"We need to understand that there are some patterns of differences between
populations," says Joseph Graves Jr., an evolutionary biologist and author
of "The Emperor's New Clothes."
"Differences don't necessarily correlate with skin color, but rather with
geography and climate. Genes play a major role."
East and North Africans, runners from southern Europe and those from high-altitude
regions in Asia and Latin America are more likely than whites of northern
European and West African descent to win distance races because they are
born with a biomechanical package for endurance activities: lean, ectomorphic
physiques, large lung capacity and a preponderance of slow-twitch muscle
fibers. All the training in the world is unlikely to turn an African-American
into an elite marathoner--or a Kenyan into a top 100-meter runner.
Populations that trace their ancestry to West Africa have an almost perfect
biomechanical package for sprinting and jumping: small, efficient lungs
and a naturally high percentage of fast-twitch muscles. While American
blacks and athletes from West Africa are not good distance runners, they
hold the top 200 and 494 of the top 500 times in the 100 meters.
On the other hand, the fastest 100 meters ever run by a Kenyan is 10.28
seconds, ranking 5,000th on the all-time list.
Although there have been great white runners in the past, the domination
evident in the past by the Flying Finns or the great Anglo runners from
Britain, Ireland and the U.S. is a thing of the past. By and large, white
runners do not have the lean physique necessary to dominate distance running
or the explosive kinetics of athletes of West African ancestry to excel
regularly in sprinting.
According to scientists, white athletes will continue to dominate in power
sports such as weightlifting, the shot put, the discus and the hammer
throw because of superior upper-body strength.
Could a native-born American win Chicago again? Certainly. In the not-too-distant
future, naturalized Americans from East and North Africa will be having
children of their own. That's the beauty of the great American melting
pot. And as a result of natural variation and the roulette wheel of the
human spirit, there will always be great runners from every part of the
globe, including America. But genes do circumscribe possibility, or "innate
Humans are different, and society pays a large price for not discussing
this subject openly, if carefully. Events such as the Chicago Marathon
provide an opportunity to broaden our understanding of the genetic revolution
