In one hour 59 minutes and 30 seconds, the 31-year-old Kenyan rewrote the boundaries of possibility. While the great Eliud Kipchoge became the first man to run a marathon in under two hours in 2019, that was not record-eligible as it was held under controlled conditions. Remarkably, Sawe was joined in the record books by Ethiopia's Yomif Kejelcha, who finished second with an astonishing time of 1:59:40 to become just the second man to finish a marathon in under two hours. In the women's event, Ethiopia's Tigst Assefa improved her own world record by nine seconds to set a new time of 2:15.41. In a sport of 'marginal gains', all eyes are on how the trio thrived on a record-breaking Sunday in the capital. The answer, many feel, is in the shoe. What shoe did Sawe, Kejelcha and Assefa wear?All three athletes wore Adidas' Adizero Adios Pro Evo 3. The shoe was launched on 25 April, just two days before the world's best took to the streets of London. It is the third iteration of a hugely popular shoe. Adidas worked with Sawe, Kejelcha and Assefa over the last three years to produce this version of the trainer.In Sawe's case, it helped him break Kiptum's London course record of 2:01:25 by nearly two minutes. Sawe thanked Adidas for making what he said were best shoes he had worn, particularly highlighting how "very light" and stable they are.Image source, Getty ImagesImage caption, Assefa bettered her own world recor...
