Speed glitch question.

[gigadork]

Ok so here's my problem, my friend was playing normally but then he got dc'd right? so he had to reset the internet cause it wasn't working. then when he got back into the game he instantly (on bridge) made it to the goal (we were red). he doesn't know why it does this and its only for his computer with his character. I don't know what he did but i am interested in why its doing what its doing. Suggestions? Another thing, just so you know, he runs super fast not "teleporting".
