About two years ago I did what you're going to do. From St. Jean Pied du Port to Roncavalles will be a few hours of uphill. It will never be super steep as this is the easiest pass over the Pyrennees. And the great news is, once you get to Roncavalles, the next 80 km to Pamplona is downhill ALL THE WAY!!! That part is a HOOT!!! Was the best part of the whole Camino de Santiago.
EDIT: I just realised you won't be going the same way I did. Will you be doing the Camino?
