Good question. I think the RAW is a little weird in this case. Not only can you not automatically move past them, but the situation is undefined because you only continue your movement if "you succeed in knocking your opponent prone". Since you don't knock him prone, you can't succeed in knocking him prone.kmdietri said:If a target is prone when you begin your overrun you will still draw an AoO but you can automatically move past them?

Ignoring that oddity, I'd say you can succeed at knocking him prone (even though he's already prone) and move on. But, it's not automatic. I'd further apply a houserule that gives the prone individual a -4 on the block-check.
