On land, a gator is only a threat if you come very close (i.e.about the length of the animal or less). They can lunge, but they really can't run.

They're ambush predators; if they know you can see them, they absolutely won't pursue you. They'll only attack if they think you're a threat. As long as you keep some space between you and an alligator on land, you're completely safe.

Also bear in mind that alligators prefer smaller prey than crocodiles. And that assumes they're looking for prey on land, which is almost never the case; they strongly prefer to ambush prey from the water.

Crocodiles can actually gallop. They''re the only reptiles that can do this. But alligators have never been seen galloping, and when crocodiles do it, it's always to escape a threat - not to catch prey. And they can't do it very far.
