And there were essentially no roads, just tracks. And often not even that, so that one had to travel through thick forest and swamps. And forget about bridges. And you had to pitch camp every night as settlements were few and far between. On foot, fit males traveling very light could cover this distance in three to four weeks under the best of circumstances. A lot longer when transporting goods. Even on horse, an unencumbered messenger would need about a week. Poland at that time wasn't anything like France or England where the Romans left good road systems behind. If the weather was bad. you could double or triple those times.
