Assuming I understand the way the clone behaves, then;
Identify any large, sharp, pointy objects. Like, large broken panes of glass, sheets of metal, rebar, etc.
Line myself with a clear straight path, and run, and dive forwards onto the ground, in some sort of belly flop.
Quickly adjust the pointy object to be in the location at which I landed.
Wait for the clone to charge and impale himself.
