Well, considering Spidey is one of the most dexterous people in the Marvel universe. It's not too much to assume that he could probably sense and react to The Flash, for a certain amount of time. And, with Spidey's troll-belt-light, and the fact that Flash's momentum is a double-bladed sword, it's incredibly possible that Spidey can end it fast and win, but only if he does it fast. The longer the battle draws out, the more tired Spidey will be, and the harder it will be to sense and react to Flash.
