Ketchell's solution was to dig up the roundabout and start again, turning the -2% camber into a +1% one. Good for taking rainwater away from a tourist attraction, terrible for a marathon runner trying to make an about turn while travelling at 13mph. The presence of a historic building in its centre meant that the road had been designed with a -2% camber. He is a man well schooled in sport's one percent advantages - the so-called marginal gains. Why? As a data scientist Ketchell has helped Team Ineos (formerly Team Sky) win three Tours de France. For the next four hours until sunrise, he kept a one-man watch over this hump in the road - a pivotal piece in the complicated jigsaw of Kipchoge's 1:59 Challenge. Ketchell was desperate to check nobody was trespassing on a small roundabout that had been his second home for the past two weeks. He was so unsettled that he jumped out of bed and hotfooted it 3km across Vienna. Plus, he had a rotating cast of pacers not permitted in record-eligible runs, was also handed bottles of Maurten from a bike, and benefited from a pancake flat runway lined with cheering fans.But 3,500 miles away in Austria, American scientist Robby Ketchell was woken by a nightmare at 3am. First, he’s clearly the “GOAT,” holding the official world record and is undefeated in his last 10 marathons, including a gold medal at the 2016 Olympics in Rio. Of course, the shoe isn’t the only factor in Kipchoge’s historic run. The patent drawings, recently unearthed by the site Believe in the Run, outline a cushioning apparatus that includes a segmented sole, three plates (likely carbon fiber), and up to four fluid-filled chambers. patent filed by Nike in 2018 that looks extremely similar to Kipchoge’s Vienna shoe. We’ll get a better look at the prototype as images from the INEOS 1:59 Challenge surface, but until then, we’ve got something better: A U.S.
