He actually has to use his time powers in order to run fast, meaning that he has to react fast. I'm not entirely sure how fast he can actually use his time powers, so I can't give an exact answer but Thor could probably throw the Mjolnir at him depending on how far away the two are.

And this is a thread about Ben vs Thor. Ben being shit should be taken into account, and that's another reason why Thor would defeat Clockwork (and more importantly, Ben).
