BMX Racers Roll With
Latest Methods
By GREG BISHOP
CHULA VISTA, Calif. —
When Mike King raced BMX bicycles, the sport’s elite knew nothing of dynamic
warm-ups, or core cooling, or thermal regulation. They did not mix sports
drinks for maximum hydration and electrolyte balance.
They were BMX riders, and
they resided at the intersection of counterculture and extreme sports, and the
very idea of science as a means to improvement seemed downright uncool. This
was before bicycle motocross became an Olympic discipline, before King became
an Olympic coach, before his sport and its outdated training methods underwent
a scientific revolution after its debut
at the 2008 Summer Games in Beijing.
At a recent practice,
King looked less like an employee of USA Cycling and more like the BMX pioneer
he was in what now seems like another life. He wore a mesh hat cocked sideways
and low-hanging shorts, his face covered in stubble, eyes hidden behind
sunglasses.
King paused and
considered how to answer a question about his team’s so-called magic pants and
their powers of recovery.
“Magic pants?” King said
as he grimaced slightly. “I really can’t discuss them.”
That Belichickian
response showed how much BMX has evolved since the Beijing Games, transformed
from rebellious adolescent into, King said, “something more grown-up.” As he
spoke, the team’s video coordinator, wearing a hooded sweatshirt, recorded
practice runs from a nearby roof, beaming the images and data to the iPads of
coaches on the course.
One of those coaches,
James Herrera, started in BMX in 1977. As he gravitated toward coaching, he
focused on less developed training methods, returned to school and obtained
master’s degrees in psychology and exercise physiology. Such methods sounded,
at first, like a foreign language to his charges.
When King raced,
advancements in strategy came mostly from watching competitors or reading
textbooks. The basics: climb on small bike, pedal furiously, turn left, repeat.
The riders traveled together, ate together and sometimes bunked together, a mix
of French and British and Australian, with as much camaraderie as competition.
Some of the more serious
athletes transitioned into other cycling disciplines. The British track cyclist
Chris Hoy, winner of three gold medals in Beijing, started in BMX.
So did his teammate Jamie
Staff, a gold medalist for Britain who became a track cycling coach for the
United States. He used to watch Christophe Leveque, the Flying Frenchman, who
dominated BMX throughout the 1990s with support from French sports federations.
Staff and others were devoted, riding for six to eight hours daily. But that
training, Staff said, was “misguided” and “uneducated.”
When the sport made the
Olympic stage, other nations followed the Leveque model. BMX training became
more like track cycling training, which had become more like road cycling
training, with a process similar to the one used by Tour de France
teams.
“It’s getting really
scientific, which is not really BMX,” Staff said. “I know they’re trying to keep
BMX cool and hip and trendy. At the same time, they’re changing the mentality.
At this point, you buy into it. Or you don’t bother.”
When the 2008 Olympics
rolled around, King concentrated on keeping his athletes relaxed. He knew the
pressure and the magnitude would be higher than ever.
It felt, he said, like a
culmination: BMX, at the highest level of sport, on prime-time international
television; BMXers in the opening ceremony, clad in red, white and blue. This
meant more money, more exposure, more legitimacy as a sport.
One future Olympian
watched the event on television. His name is Connor Fields. He is a favorite
for this summer’s London Games.
“The impact couldn’t have
been bigger,” he said. “The Olympics justified and solidified everything we do.”
The minute the races in
Beijing ended, another race began, and the United States program was caught
flat-footed. The American men and women had seized half the Olympic BMX medals
because they possessed the deepest talent pool, because the sport was created
and incubated in Southern California.
That would no longer be
enough, not after Australia, France and other countries put their considerable
resources — more private financing and sports institutes — behind BMX in late
2008. The United States, Herrera said, fell “maybe a year behind.”
At the same time, King
and company shifted their junior development strategy. They went for youth,
replacing veterans with prospects, save for Mike Day, the elder statesman and a
silver medalist in Beijing.
The United States
retained the largest talent pool but needed to take a more scientific approach
to training. Herrera was mindful of the pattern in another cycling discipline.
Mountain biking, he said, was also created in the United States, yet an
American last won an Olympic medal in that sport in 1996, its first year in the
Games.
The American BMX program
underwent a training overhaul. Herrera came onboard. Simple dietary changes
were instituted: no dessert or sugary energy drinks; more fruits and vegetables
and nutritional supplements. Jerseys were designed to be tighter and more
wind-resistant.
Coaches studied different
exercises in the gym and measured their effects on the bike. They added power
meters, as had been done in the other cycling disciplines. Based on the data
they accrued, they adjusted the volume of on-course training and its frequency,
determined whether riders needed more practice on uphill or downhill sections,
and selected gear.
They hired a videographer
who used the computer program Dartfish to show riders the best lines to take on
a given turn. Videos of individual riders could be placed side by side on a
screen, as if they were racing, to compare which one took the most direct
route.
In most elite BMX races,
Herrera said, the winner finishes less than a second and a half ahead of the
competitor who finishes 64th. Often, the gap is less than one second.
“In my era, we’d probably
roll our eyes,” King said. “But at this level, with the money we spend, 1
percent of improvement based on sports technology could be one thousandth of a
second, which could be the difference between a gold and silver medal.”
Before the 2008 Games,
the United States built a replica of the Beijing course at the Olympic Training
Center here. Each year, it hosted an official race. Day won the first one in
35.9 seconds. Fields won the most recent one in 33.6, a difference, he said, of
10 to 20 meters.
Those gains, which
Herrera described as massive and astronomical, came in large part because
Fields, 19, emerged during BMX’s scientific revolution. His coach, Sean Dwight,
said BMX, with athletes on tiny bikes traveling down steep ramps in three
seconds at 40 miles an hour with seven other competitors to contend with, was
more explosive than the 100 meters in track and as explosive as weight lifting.
Dwight focuses most on
Fields’s biomechanics, believing that an ideal position on the bike produces
maximum power. He knows almost immediately whether Fields’s head is tilted two
inches the wrong way, or his shoulders are too far back.
While Fields helped push
BMX into this new territory, the courses grew longer, the jumps higher, the
turns more dangerous. If this made BMX more viewer-friendly, it also worried
coaches.
The replica London course
sits near the replica Beijing course, and it appears at least twice the size
and twice as difficult. The first jump, Herrera said, is the length of three to
three and a half cars. King said BMX had “reached its threshold,” just as he
said four years ago. Asked if the progression meant somebody could ultimately
die, he said, “I hope not.”
Regardless, the
scientific revolution will continue. King said riders were once ridiculed for
acknowledging that they took ice baths. He laughed and called the progress
mind-boggling, adding, “You know, it’s still a bike race.”
He won plenty of those
without science, but the United States had no gold medals in Beijing. If to win
a gold meant that BMX had to lose some of its counterculture cool, well,
consider King a convert, magic pants and all.
