The more I think about this, the more I think the fight would be decided within the first 30 seconds or minute.
It is always quite possible that Gregor could deflect Hagrid's first swing, not through brute strength alone but by footwork (moving to the side, so Hagrid's blow is a glance) and spin to come up behind Hagrid, hamstringing him in the backswing. If Hagrid goes to his knees, unable to rise, it's over for Hagrid.
If Hagrid gets one solid blow, most likely with the shield, Gregor's probably lost his advantage in agility and couldn't prevent Hagrid's next attack–due to unconsciousness or at least severe disorientation.
An extended fight would probably go to Hagrid. IF Gregor possessed the kind of cleverness that Oberyn possessed, and more of The Viper's fighting style, he could probably last awhile; but, I don't think he does. He's more likely to engage rather than avoid Hagrid's attacks. OTOH, seeing Hagrid before him might be enough for Gregor to change up his style.
