You can clearly see how Rupp is running in a leagal yet very dirty tactic, sitting on the leader’s tale like an Alabama tick, I hate when runners do that, it’s so dirty. You could see it bothers the leader, he tried to get rid of him a few times moving to the side, but Rupp just kept riding on him like a leach. Kipchoge hates runners that do that to him, he always marks them to move a side or to go forward and run their own pace by pointing with his finger to them. He did that to Lelisa and to Adola in Berlin.
why is it dirty?
because it uses less energy? do you go out and hobbyjog your races in a pure way, never sitting behind anyone when you are hurting and step in front to break the wind for everyone behind you?!
i bet you don't.
you don't know anything, NOP may have even paid those guys to pace him, who the heck knows.
i think you are one of those people who would rather lose leading a race than winning by racing smart and drafting, like Prefontaine. It didn't get him much on the international stage, and rarely does it work these days in longer races.
