![]() Runners everywhere will be watching closely. Then again, he’ll still be sporting the latest in shoe technology, which will be tested in real-world conditions. After all, a successful marathon has always been about managing the day, which means adjusting for the weather, course and fellow competitors - all of which test the mettle of even the best runners. The true test of technology and Kipchoge will occur during his next official marathon where conditions aren’t controlled. He held an unbelievable 2:50 min/km pace for 42 kilometres and looked like he had plenty of gas left in the tank when he crossed the finish line, despite his blistering pace. VO 2 max or your oxygen uptake shows how much oxygen your body absorbs and uses while working out. The International Association of Athletics Federations has addressed the controversy surrounding the technology-laden Vaporfly 4%, which sells for $330, stipulating that “any type of shoe used must be reasonably available to all in the spirit of the universality of athletics.” The association also states: “Shoes must not be constructed so as to give athletes any unfair assistance or advantage.”Ĭertainly, Kipchoge’s numbers lend credence to this claim. ![]() To further illustrate the effect of Vaporflys on performance, it’s worth noting that from 2006 to 2018 only one or two runners broke 2:12 at the Chicago Marathon this year’s race, which took place Oct. The shoes, which feature a noticeably higher stack than traditional running shoes, have users commenting that they feel like they’re running on trampolines. How big a deal are these technology-forward shoes? Since their debut in 2017, marathoners and half-marathoners wearing Vaporflys ran three to four per cent faster than their previous personal bests. Add a flat course with limited turns, the perfect weather conditions (no wind, not too hot or too cold) and pacers to block wind resistance, and you’ve got an almost full set of winning conditions - all of which were in place for Kipchoge’s successful run this month. Superior running economy translates into less energy (oxygen) expended at a given pace, which leads to faster times compared to a less efficient runner with a similar VO2 max. Nike played an Oscar-worthy supporting role in the most significant distance-running achievements of Eliud Kipchoge. Some degree of each of these pillars of marathon running is genetically determined and some can be improved with training, but when it comes to being the best of the best, most experts believe that running economy is the biggest contributor to podium performances. So to manage an assault on the 2-hour marathon, Eliud Kipchoge breaking 2 required Nike researchers to simultaneously predict, challenge, and technologically supplement a group of elite athletes’ innate abilities. Article contentĪll top marathoners benefit from three distinct physiological properties: an impressive VO2 max, an economical stride and the ability to run an entire marathon at the top end of their lactate threshold ( the maximum effort an athlete can sustain for a specific period of time).
