Ultra Marathon Man 

Even among long-distance runners, S.F.'s Dean Karnazes is a phenom

As an ultrarunner continues to train, he develops more capillaries, bringing still more oxygen to his muscles. His level of metabolic enzymes -- proteins that break down carbohydrates and fats -- more than doubles. And his body builds up more tolerance to lactic acid, an exercise byproduct that causes muscle soreness. That means he can run faster and harder without experiencing muscle cramps.

According to Dahlkoetter, ultrarunners tend to be neurotic about their diets, and Karnazes is no exception. He eats no refined sugar and very few carbohydrates -- except during his races, when he gorges on anything from Big Macs to entire pumpkin pies to replace the calories he burns. "I'm a lightweight now," he says. "When I drink one beer I'm buzzed."

He runs between 85 and 120 miles a week. Either he runs at 4 a.m., before taking his 9-year-old daughter Alexandria to school, or after he puts her and his 6-year-old son Nicholas to bed at night. On weekends, he often runs from his home in lower Pacific Heights across the Golden Gate Bridge, up to the top of Mount Tamalpais, down to Stinson Beach, and back home again -- a distance of 43 miles.

Terry Hunt, Karnazes' business partner, recently scheduled a brainstorming meeting for them at a Menlo Park tennis club. Both men's families were invited, so their wives could meet and their kids could swim in the pool. When Hunt called the morning of the get-together to make sure Karnazes had directions, Dean's wife, Julie, informed Hunt that her husband had left the house four hours ago -- on foot. Running on roads and trails -- "Like a gazelle!" marvels Hunt -- Karnazes arrived at the club right on time. "It didn't even look like he'd been running," says Hunt. "He wasn't sweating." His partner proceeded to swim laps in the pool with his son riding on his back.

In a sport whose participants are plagued with knee and foot injuries, Karnazes says he's never been hurt, never even pulled a muscle. He seemingly improves with age; last year, he had his best year yet, with his impressive showing at the Western States and his near-win in the Badwater Ultramarathon.

Karnazes' amazing ability can be attributed in part to his perfectly even footfalls. When walking and running, most people either pronate, which means they land on the insides of their feet, or supinate, which means they land on the outsides of their feet, says Dr. David Hannaford, a San Francisco podiatrist who has treated many ultrarunners and knows Karnazes. Under the repetitive stress of ultra-distance running, an off-center footfall can produce pain if not corrected by the right shoes or by molded plastic inserts called orthotics. But Karnazes, says Hannaford, has what's known as a "true foot strike." That is, his foot lands evenly on the ground, making him less prone to injury.

"Dean is pretty lucky," says Hannaford. "He's a natural athlete."

Most runners are gaunt and scrawny, streamlined for speed. But Karnazes, partly thanks to good genes and partly because he does other sports like surfing and mountain biking, has a muscular upper body and big, powerful calves.

Dr. Jeff Shapiro, a Bay Area physician and race director of the Providian Relay, has studied the biomechanics of running and developed a technique for ascending hills more efficiently. It involves leaning forward from the ankle, which reduces knee stress and makes you less tired while climbing. After teaching his technique to hundreds of runners with good results, Shapiro taught it to Karnazes, and got no results.

"I've gone over it with him three different times and expected him to try it once or twice," says Shapiro. "But his legs are so strong, it's almost as if he doesn't need it. We run up [Lyon Street] and I'm doing the technique and he's not, and he's way ahead of me. The only time I beat him up the hill was because he got a phone call."

Karnazes and his family live in a five-bedroom Victorian with the austere, partially furnished look of a home where the parents are waiting until their kids are out of the bull-in-a-china-shop stage before they decorate. There are no trophies or framed photos of Karnazes crossing finish lines -- at least not downstairs where the family receives company.

"I try to keep my running from cutting into my family life," says Karnazes.

That's probably a good idea, says sports psychologist Dahlkoetter.

"A lot of people get into ultras as a couple," she says. "But if one gets into ultras and the other one doesn't, it can pull people apart because it takes up so much time. It becomes the type of thing only ultrarunners can understand, and you see people getting divorced."

Karnazes' wife Julie doesn't run unless, as Karnazes jokes, "someone's chasing her." A petite, put-together blonde with a successful San Francisco dental practice, she met Karnazes when they were high school freshmen in San Clemente, where both grew up. Karnazes' feats of endurance don't strike Julie as anything extraordinary; that's all she's ever seen him do.

"I never thought to ask him that," Julie says, perplexed, when questioned about how her mate is able to push through pain and mental blocks to finish his long runs. "I guess I just always assume he'll succeed -- I've never in my life seen him fail at anything physical."

  • clipping at Brava Theater Sept. 11
    Sub Pop recording artists 'clipping.' brought their brand of noise-driven experimental hip hop to the closing night of 2016's San Francisco Electronic Music Fest this past Sunday. The packed Brava Theater hosted an initially seated crowd that ended the night jumping and dancing against the front of the stage. The trio performed a set focused on their recently released Sci-Fi Horror concept album, 'Splendor & Misery', then delved into their dancier and more aggressive back catalogue, and recent single 'Wriggle'. Opening performances included local experimental electronic duo 'Tujurikkuja' and computer music artist 'Madalyn Merkey.'"
