Some people say he ‘only’ drafted in the first half, and that that did not influence the result. Right. Look about 44 / 45 / 46mins into the race. There is a guy hanging out the roof of the lead car. Maybe the race director? He is waving his arms to Kiplimo to direct him left or right of the streets. Multiple times. He seems to be communicating with the driver too. Kiplimo sees it and follows the directions. Sometimes the car has a slightly bigger gap than a few meters, then slows down. Sometimes Jacob is not running directly behind the car, the cars steers right to correct it. Another time the runner - after a tight corner - swerves outwards, he then moves back in line with the car straight away, probably feels some wind. And so on.
Kiplimo is right, it is allowed, so why not? His record will count (*pending ratification for everything else of course) However, it is intentional from the part of the organisation , they want to ‘help’ him by creating the opportunity to draft. They are very well aware of the value of an exceptional time.
So questions about fairness and the spirit of the sport and rules and - in the end - credibility - have to be asked, or not?
