I straddle my bike, clip into my pedals, and take a sluggish, deep breath. What I am about to do will not take lengthy, however it is going to harm and I do know it. Actually, it is all I can take into consideration.
My bike is hooked up to a stationary coach that controls how arduous I need to pedal to show the cranks. Controlling the coach is Evelyn Stevens, an Olympic bike owner who, in 2016, set a world document in one in every of her sport’s most celebrated—and most masochistic—occasions: the hour report.
The hour is extensively thought-about to be biking’s purest document, albeit an uncommon one: As an alternative of requiring them to traverse a set distance, this occasion allots cyclists a set time of 60 minutes to pedal as many laps as they will round a velodrome. And whereas different aggressive pursuits sometimes pit a number of athletes towards each other, the hour is a solo affair. The race, in the event you can name it that, is towards the clock.
And towards your self.
“The whole point is to push your body and your mind to a place they’ve never been before,” says Stevens, who just lately visited WIRED’s workplaces in San Francisco to offer me a style of what it is wish to pedal one’s ever-living brains out. That is what the bike and coach are for: to see how lengthy I can keep the facility output of a world-class hour-record bike owner.
Athletically talking, I am not a world-class something—however I am no slouch, both: I have been a runner all my life, raced triathlons in school, and have accomplished a number of marathons. Nonetheless, as I start pedaling, I can not assist considering how unprepared I’m for the duty at hand. Not simply bodily, however mentally.
Stevens spent years getting ready her mind and physique for a go on the hour document. She labored on cultivating mindfulness with a sports activities psychologist. She floated for hours inside sensory deprivation tanks, to apply untethering her ideas from the passage of time. She educated with out music, and, extra importantly, with out biometric suggestions: The Union Cycliste Internationale, the governing physique of the biking world, mandates that hour-record athletes fly by really feel, with out information of metrics like coronary heart price, velocity, cadence, or energy output. The level of Stevens’ psychological coaching was to apply decoupling her consideration from all the things however the current second. To focus her consideration not on the ache, her thirst, or how lengthy she had ridden, however particular person pedal strokes. “My mantra was pull, pull, push. Pull, pull, push. Pull, pull, push,” she says.
Regardless of her preparation, Stevens’ hour try almost broke her. Throughout minutes 50 by way of 55, “I was physically in the most painful place I had ever been,” she says. She remembers sounds fading away, her imaginative and prescient going darkish, and her ideas turning to all of the improper issues. “You want oxygen, you want water, your body is screaming: Stop, stop, stop.” Across the 55th minute, the thought of letting down her coach introduced her again. “I just thought, oh gosh, he’d be so disappointed. His family, who sacrificed so much of their time with him so he could coach me, would be so disappointed!” The guilt returned her consideration to her breath, to her mantra, to the frame of mind she wanted to traverse a then-unprecedented 47.98 km—29.81 miles—in 60 minutes flat.
A couple of minutes into my warmup, my shirt already sopping with sweat, it happens to me: I haven’t got a mantra. Although if I did, it might in all probability be one thing like “don’t hurt yourself.” Or slightly, as a result of the ache element of this little stunt is non-negotiable, “don’t vomit.”
To face a shot on the hour document, an athlete should keep for 60 minutes an influence output that most individuals would wrestle to carry for 60 seconds. Stevens averaged simply over 300 watts all through her try. British bike owner Bradley Wiggins, who, in 2015, pedaled 54.526 kilometers (33.881 miles) to set the present males’s report, is estimated to have averaged 440 watts. When you’ve ever paid consideration to your numbers throughout spin class, these figures will little question astound you. If spinning’s not your factor, think about this: 440 watts is the power it takes a 150-pound individual to climb a flight of stairs in about 5.5 seconds. Now think about climbing 655 flights at that tempo. That is an hour.
To maintain that sort of energy output for an hour takes extra than simply intense bodily coaching. It additionally requires critical physiological presents. Arguably the best present of elite cyclists is an innately excessive capability for pulling oxygen out of the air and delivering it to their tissues. Sport scientists name this measurement VO2 max, or maximal oxygen uptake, and categorical it in milliliters of oxygen per kilogram of physique weight per minute. The common individual has a VO2 max within the 30s or 40s. Stevens’ VO2 max? “Seventy-two, seventy-three,” says sport scientist Neal Henderson, who coached Stevens to her hour document. That quantity is astonishing. Most well-trained athletes rating within the 50s or low 60s. “Women in the 70s is like men in the 80s,” Henderson says. “There’s a handful in the world.”
VO2 max performs such an essential position in biking efficiency that on uncommon events, an individual with anomalously excessive maximal oxygen uptake will go many years with out absolutely realizing their athletic potential, solely to encounter it comparatively late in life. Stevens was such an individual. At 25, she was working full time on Wall Road when, on a go to to California within the fall of 2007, her older sister inspired her to attempt biking. She beloved it. Lower than a yr later she raced Vermont’s Inexperienced Mountain ladies’s race as an novice and completed 4 minutes quicker than the professionals. In 2009 she give up her job in finance and went professional. Six months later she positioned second within the US Nationwide Time Trial Championships. In 2010 she positioned first. In 2011, she did it once more. In 2012, she represented the US within the Olympics.
“I got to a point where I wanted something new, something different, something challenging,” she says. She discovered that one thing within the hour report.
To pursue the document in earnest, Stevens wanted greater than her freakish power and preternatural cardio talents. She additionally wanted a high-performance journey. She selected a modified model of Specialised’s Shiv. Like many trendy time-trial and triathlon bikes, the carbon-fiber body’s bladelike form is optimized to slice the air with as little resistance from the wind as potential. Her wheels, too, have been designed to scale back drag, as was her helmet: a clean bubble of froth and plastic with a menacing rearward taper harking back to the xenomorph from Alien.
Becoming Stevens to her bike concerned lengthy hours in Specialised’s bespoke, human-sized wind tunnel. In 2014, the UCI modified the principles for the hour by permitting riders to exchange their conventional drop handlebars with drag-reducing “aero bars.” Cyclists might now lean far ahead by resting their forearms atop their handlebars, minimizing the world uncovered to wind resistance as they journey. However the aero place has its drawbacks. Leaning too far ahead saps your energy; incline too far again, and also you’re preventing wind resistance. Discovering a bike owner’s goldilocks posture is hard. Discovering the pose they will truly keep in is even more durable: The optimum aero place is often too uncomfortable to take care of for an hour, and often leads to shorter distances than a much less aggressive tuck that riders can maintain for the complete 60 minutes. The aero place, in any case, is simply aero once you’re in it.
Again in WIRED’s workplaces, with Stevens controlling my stationary coach, I haven’t got to fret about steering my bike, or take note of the place of my physique. All I’ve to do is pedal. However when my warmup ends and Stevens begins growing the wattage on the coach in 50 watt increments, my thoughts shortly turns to the searing in my quads. At 250 watts she asks the way it feels. “Hard,” I inform her between gasps. I am making an attempt to take care of my composure, however my physique’s already in overdrive.
We graduate to 300 watts, roughly the facility Stevens maintained for her hour document. I attempt to play it cool, maintain the trouble. The unique plan was to spend 30 seconds at every wattage, however I barely handle 15 earlier than Stevens notices me struggling and intervenes. “This looks like kind of an uncomfortable level,” she says, smiling. An understatement. If we do not ramp up now, I am going to by no means get to expertise Wiggins’ 440 watts. She will increase my resistance on to 400 watts, then jumps proper to 440. “So remember, he did this for 60 minutes,” she says. “What do you think, Robbie—can you do it for an hour?”
I can’t. I final 45 brutal, sweat-drenched seconds.
Afterwards I’m completely wiped, and my legs are sore for the subsequent a number of days. I am astonished to study that cyclists will sometimes make two hour-record makes an attempt kind of in sequence. Coincidentally, that is exactly what Vittoria Bussi does the day earlier than Stevens visits WIRED’s workplaces: On her second try in as many days, the Italian bike owner set a brand new UCI ladies’s hour document, driving 48.007 kilometers (29.83 miles), beating Stevens’ greatest by 27 meters.
It is anybody’s guess how lengthy Bussi’s report will stand. Stevens held the title for 2 and a half years, however Henderson, her coach, thinks that, beneath present UCI guidelines, the correct lady, astride the correct bike, circling the perfect monitor on an excellent day, might greatest Bussi’s efficiency by two entire kilometers, breaking the 50 kilometer barrier for ladies. Beneath equally optimum circumstances, he says, the best man may eke out 57.
Henderson bases these estimates on arduous measurements: Rider weight. Energy output. Wind resistance. The elevation of the monitor and the density of the air above it. “His approach is much more scientific than mine,” says Stevens, who retired from biking shortly after her go on the hour. “I feel like nothing is impossible. It only becomes possible.”
