СКАЧАТЬ psychological, and environmental factors that would need to come together for someone to run a two-hour marathon. After reviewing mountains of data and consulting experts around the world, including Joyner, I presented ten pages of charts, graphs, maps, and arguments, concluding with my own prediction: the barrier would fall, I wrote, in 2075.

      That prediction leapt immediately to mind in October 2016, when I got an unexpected call from David Willey, then the editor in chief of Runner’s World. Nike, the biggest sports brand in the world, was preparing to unveil a “top-secret” project that aimed to deliver a sub-two marathon in just six months. We were being offered the opportunity to go behind the scenes to cover the initiative, which they’d dubbed Breaking2. I didn’t know whether to laugh or roll my eyes, but I couldn’t say no. I agreed to fly to Nike’s headquarters, in the Portland, Oregon, suburb of Beaverton, a few weeks later to hear their pitch. If someone had to debunk an overhyped marketing exercise, I figured the research for my earlier Runner’s World piece had left me as well equipped as anyone.

      As my guest spot on the television broadcast wraps up, Kipchoge hits twenty-three miles. It’s May 6, 2017, exactly sixty-three years to the day after Roger Bannister ran the first sub-four-minute mile. I’m nearly frantic to get track-side now—but I’m not sure how to get down from my lofty perch in the broadcast booth. Peering over the edge, I briefly contemplate swinging myself over the railing and risking the drop. But a stern glance from a nearby security guard dissuades me. Instead, I head back over the causeway that connects the broadcast booth to the main building’s multistory maze of dead-end hallways and unlabeled doors. I don’t have time to wait for a guide. I break into a run.

CHAPTER 1

       The Unforgiving Minute

       If you can fill the unforgiving minute

       With sixty seconds’ worth of distance run,

       Yours is the Earth and everything that’s in it … .

      —RUDYARD KIPLING

      On a frigid Saturday night in the university town of Sherbrooke, Quebec, in February 1996, I was pondering—yet again—one of the great enigmas of endurance: John Landy. The stocky Australian is one of the most famous bridesmaids in sport, the second man in history to run a sub-four-minute mile. In the spring of 1954, after years of concerted effort, centuries of timed races, millennia of evolution, Roger Bannister beat him to it by just forty-six days. The enduring image of Landy, immortalized in countless posters and a larger-than-life bronze statue in Vancouver, British Columbia, comes from later that summer, at the Empire Games, when the world’s only four-minute milers clashed head-to-head for the first and only time. Having led the entire race, Landy glanced over his left shoulder as he entered the final straightaway—just as Bannister edged past on his right. That split-second tableau of defeat confirmed him as, in the words of a British newspaper headline, the quintessential “nearly man.”

      But Landy’s enigma isn’t that he wasn’t quite good enough. It’s that he clearly was. In pursuit of the record, he had run 4:02 on six different occasions, and eventually declared, “Frankly, I think the four-minute mile is beyond my capabilities. Two seconds may not sound much, but to me it’s like trying to break through a brick wall.” Then, less than two months after Bannister blazed the trail, Landy ran 3:57.9 (his official mark in the record books is 3:58.0, since times were rounded to the nearest fifth of a second in that era), cleaving almost four seconds off his previous best and finishing 15 yards ahead of four-minute pace—a puzzlingly rapid, and bittersweet, transformation.

      Like many milers before me and since, I was a Bannister disciple, with a creased and nearly memorized copy of his autobiography in permanent residence on my bedside table; but in that winter of 1996 I was seeing more and more Landy when I looked in the mirror. Since the age of fifteen, I’d been pursuing my own, lesser four-minute barrier—for 1,500 meters, a race that’s about 17 seconds shorter than a mile. I ran 4:02 in high school, and then, like Landy, hit a wall, running similar times again and again over the next four years. Now, as a twenty-year-old junior at McGill University, I was starting to face the possibility that I’d squeezed out every second my body had to offer. During the long bus ride from Montreal to Sherbrooke, where my teammates and I were headed for a meaningless early-season race on one of the slowest tracks in Canada, I remember staring out the window into the swirling snow and wondering if my long-sought moment of Landyesque transformation would ever arrive.

      The story we’d heard, possibly apocryphal, was that the job of designing the Sherbrooke indoor track had been assigned to the university’s engineering department as a student project. Tasked with calculating the optimal angles for a 200-meter track, they’d plugged in numbers corresponding to the centripetal acceleration experienced by world-class 200-meter sprinters—forgetting the key fact that some people might want to run more than one lap at a time. The result was more like a cycling velodrome than a running track, with banks so steep that even most sprinters couldn’t run in the outside lanes without tumbling inward. For middle-distance runners like me, even the inside lane was ankle-breakingly awkward; races longer than a mile had to be held on the warm-up loop around the inside of the track.

      To break four minutes, I would need to execute a perfectly calibrated run, pacing each lap just two-tenths of a second faster than my best time of 4:01.7. Sherbrooke, with its amusement-park track and an absence of good competition, was not the place for this supreme effort, I decided. Instead, I would run as easily as possible and save my energy for the following week. Then, in the race before mine, I watched my teammate Tambra Dunn sprint fearlessly to an enormous early lead in the women’s 1,500, click off lap after metronomic lap all alone, and finish with a scorching personal best time that qualified her for the national collegiate championships. Suddenly my obsessive calculating and endless strategizing seemed ridiculous and overwrought. I was here to run a race; why not just run as hard as I could?

      Reaching the “limits of endurance” is a concept that seems yawningly obvious, until you actually try to explain it. Had you asked me in 1996 what was holding me back from sub-four, I would have mumbled something about maximal heart rate, lung capacity, slow-twitch muscle fibers, lactic acid accumulation, and various other buzzwords I’d picked up from the running magazines I devoured. On closer examination, though, none of those explanations hold up. You can hit the wall with a heart rate well below max, modest lactate levels, and muscles that still twitch on demand. To their frustration, physiologists have found that the will to endure can’t be reliably tied to any single physiological variable.

      Part of the challenge is that endurance is a conceptual Swiss Army knife. It’s what you need to finish a marathon; it’s also what enables you to keep your sanity during a cross-country flight crammed into the economy cabin with a flock of angry toddlers. The use of the word endurance in the latter case may seem metaphorical, but the distinction between physical and psychological endurance is actually less clear-cut than it appears. Think of Ernest Shackleton’s ill-fated Antarctic expedition, and the crew’s two-year struggle for survival after their ship, the Endurance, was crushed in the ice in 1915. Was it the toddlers-on-a-plane type of endurance that enabled them to persevere, or straightforward physical fortitude? Can you have one without the other?

      A suitably versatile definition that I like, borrowing from researcher Samuele Marcora, is that endurance is “the struggle to continue against a mounting desire to stop.” That’s actually Marcora’s description of “effort” rather than endurance (a distinction we’ll explore further in Chapter 4), but it captures both the physical СКАЧАТЬ
