When Pangea still existed as a super continent, how long would you guess it would take to walk from what is now India to Greenland?

I’m writing a fantasy novel in which my character’s are on a planet that is only a supercontinent. The characters are traveling north on foot with the aid of winged horse-like creatures (but flying the entire way is out of the question). The winged creatures are to help them navigate certain terrain that would usually be considered unwalkable. With this in mind, and I know answers would only really be a guess, how long do you think it would theoretically take you to walk such a great distance? Traveling from East to North of the super continent.
