When will the comparison come out? What was different that allowed Kipchoge to run a sub2 marathon? Better to have straights than turns? Don’t have Lelisa and Tadese to worry about? He was also on pace in Monza to 30k, but the pace in Monza wasn’t as consistent as Vienna. The two pacers in the back help him, so he knows he has to keep in front of them? Where was the pace falling off in Monza? Who tripped up Kipchoge but he was still able to regain his form?
