Maybe they saved the country from an evil tyrant, now they got to move on bigger things.
That could work just as well: the party completes some joint undertaking that has legendary ramifications; this opens them all to advancement into the realm of paragons.
I think the essence of what I would do is to make sure that 10th to 11th is not merely a level up, but that it must be preceded by a genuine accomplishment of note within the campaign world.
