How Eliud Kipchoge Broke the Two-Hour Marathon Barrier
This past weekend in Austria, Eliud Kipchoge ran the marathon distance of 26.2 miles in 1 hour, 59 minutes, and 40 seconds, the first person in recorded history to break the two-hour marathon barrier, a feat once thought impossible. Wanting to know a bit more about how Kipchoge did it, I watched a pair of videos. The first was from Mike Boyd (who you might have seen learning how to kickflip a skateboard in under 6 hours) and it’s very much from an interested fan’s perspective.
Wired has been following Kipchoge’s attempts at a faster marathon, particularly the technology angle, and in their video, they talk with the Mayo Clinic’s Dr. Michael Joyner, who predicted in a 1991 paper that a sub-2:00 marathon was possible.
Boyd’s video references this paper as well. From a piece that Joyner wrote about his paper:
During the 1980s, ideas emerged about how maximum oxygen consumption, lactate threshold and running economy interacted to determine distance running performance. During medical school around 1985, I started think about how a person could run if he/she had the best laboratory values ever recorded for all three variables. I came up with an estimated time a few seconds faster than 1:58!
So how did Kipchoge run so fast? Well, the answer has to do with another interesting thing about this whole thing: his effort did not set an official world record for the marathon. From The Atlantic, The Greatest, Fakest World Record:
The planning that went into the event was a fantasy of perfectionism. The organizers scouted out a six-mile circuit along the Danube River that was flat, straight, and close to sea level. Parts of the road were marked with the fastest possible route, and a car guided the runners by projecting its own disco-like laser in front of them to show the correct pace. The pacesetters, a murderers’ row of Olympians and other distance stars, ran seven-at-a-time in a wind-blocking formation devised by an expert of aerodynamics. (Imagine the Mighty Ducks’ “flying V,” but reversed.)
Kipchoge himself came equipped with an updated, still-unreleased version of Nike’s controversial Vaporfly shoes, which, research appears to confirm, lower marathoners’ times. He had unfettered access to his favorite carbohydrate-rich drink, courtesy of a cyclist who rode alongside the group. And the event’s start time was scheduled within an eight-day window to ensure the best possible weather.
In an official marathon attempt, you’re not allowed to have pacesetters rotating in and out, refreshment via bicycle, or a pace car lighting the way. They touch on this in the Wired video, but technology has been wrapped up in human athletic achievement for more than a century at least. Compared to a runner competing in 1960 — when the record was 2:15:16, set by Abebe Bikila in bare feet — runners today have the benefit of better training techniques, superior knowledge of human physiology, better shoes, corporate sponsorships & other assistance, lightweight clothes that wick away moisture and don’t chafe, specially designed diets, better in-race nutrition, and, let’s be honest here, performance-enhancing drugs.
Drugs aside, all that is fine to use in an official marathon attempt, but racing alone with pacesetters (or downhill) is verboten. It’s always interesting where they draw the line on the use of technology in athletics. I think the most you can say at this point is that even with all these advantages, Kipchoge is perhaps the only person in the world right now who is capable of breaking the 2-hour barrier. But in two or three years? My guess is that 2 hours will be broken in an actual race in the next 5-7 years, even though a rough linear analysis I just did using men’s marathon record times since 1980 indicates that no one will run under 2 hours until 2033.
