Consider this: The Flash can run at the speed of light pretty easily. And he has often demonstrated the fact that he can go much much faster than that. Now, Spider-Man is good, don't get me wrong. But he doesn't really have a way to hit the Flash, let alone win.

On paper the flash is beyond OP. He can easily time travel and go attosecond fast. Attosecond means a second would be like a year to him. At that speed there is no character outside of speed force users that should be able to beat him.
Despite being surrounded by Thor, Iron Man, and Wanda, Black Widow is one of the most valuable members of the Avengers team. In one of the recent Marvel issues, Natasha Romanoff has proved that she can easily beat The Flash from DC.

though he can't move faster than a bullet nor see one coming, Spider-Man's Spidey-sense allows a precognition that enables him to seem to dodge bullets.
