I've run the Crim, several times, but wasn't in the position that you were. How would I know to confront him? You were given information by someone else that suspected he didn't run the entire course, that's different as you didn't figure it out yourself.
It's easy to figure out where he did it, you didn't tell anyone anything new. I live in Oakland County and like I said, have run The Crim many times. Nolan Street could save you over 3 miles. You could save 2.5 from Bradley Street to Miller. A person would still show up on the cameras in the Bradley Hills and definitely hit mats where they needed to.
Also, you said that someone else asked him, and you quoted your friend, which is it? You don't know me. If I knew someone did something deceptive, I would have went right to them and asked them point blank. You are letting your huge ego interfere with the facts. Let it go dude!
