MANY people have cheated in races and will continue to, regardless of whatever safe guards are put in place as their defense is to just deny it.
But...making up races that don't exist and finishing in front of runners that you never passed, that's another level altogether. To top it off, starting from so far back, and of course never being seen flying by anyone, NOT even one runner, is again, another level altogether.
That's the difference between this guy and dozens of others.
Someone posted about the old guy Oscar ?, getting caught a few decades ago. He denied it too but even without being "spotted" by people at check points along the way and not showing up on anyone's video, Will Cloney had balls and dq'ed him. The difference today is very few race director will do what he did whether he hits mats or not. Who starts that far back and does that? No one.
Any innocent person would be upset over the accusation and want to prove everyone wrong, but like Oscar and Rosie, they suddenly don't show up at races anymore. Big surprise, right?
