He can't run at lightspeed but he can certainly fight at light speed. This is why he is able to fight the gladiator who fights at or above light speed.
When I say speed force, I actually mean Speedforce. The Speedforce apparantly grants Flash an enourmous amount of powers and abilities.
The speedforce is an energy boost that allows him to accelerate to incredible speeds. In accelerating to those speeds the laws of physics enable the infinite mass punch.
He's still not as versatile as Thor, but his abilities are a hell of a lot more practical in combat, safe, perhaps, when Thor is flying.
Flash is a lot slower in combat, his reactions are slower, his movements are slower, and he certainly does not have the leverage that comes from being one of the physically strongest beings in the universe. Thor, in addition to being an utter beast in the strength department, can swing his arm faster than the speed of light. The same holds true for anyone that can go toe to toe with Thor. They can all do infinite mass punches because they are not immune to the laws of physics.
