all I have to say is that on Sunday Kipchoge got an absolutely massive level of cheers at the start from all of us runners anxiously packed into the Tiergarten (head and shoulders above any other competitor who they announced).
The spectators were out in mass- never a quiet moment on the course (I had heard that Berlin was sometimes maybe quieter than other courses in terms of cheering but definitely did not feel like it at all.
post run massage zone manned by dozens of PT & ART therapy trainees: my queue's pair were not runners and never want to do a marathon yet still knew all about Kipchoge and Assefa (though could not name the latter precisely). interestingly, did ask about PEDs (it was a blessedly long massage).
very large mural spray painted before the marathon in one of the neighborhoods of Kipchoge winning last yr visited by many pre and post race and copiously posted on social media
hell even my uber driver today from Togo said quite enthusiastically several times he would like to come out to watch the race next year though this was weirdly more in response to a conversation about my own running (did really quite well in the female division if i do say so myself). he was convinced if i get a coach i would be doing "tremendous things" ... i digress
So: evidence points to the fact that Kipchoge does inspire/ inspired/ will continue to inspire a hell of a lot of people in running, in hard work, and in self belief- good for the sport.
