It's a risk.
If you ready an action to attack as soon as they're within reach, and they move through your reach, i.e. they don't stop their movement within reach, you don't get to attack.
Not True. Immediate reactions are allowed to interrupt movement as long as the target has moved at least one square. There is always a risk that the enemy will end up doing something unexpected though and you lose your action.
