Redditor u/erterbernds67 plotted a map of Jon and the White Walkers’ movements since they clashed at Hardhome in season 5, and the difference in distance is pretty stark (zing!).
Game of Thrones season 7 continues on HBO, Sky Atlantic and through NOWTV on Sunday nights.
Sure, Jon has the benefits of boats and horse-drawn wagons, but the White Walkers can, you know, walk constantly without ever needing to sleep.
This is true of some characters more than others though, which has led to a chronology that’s a little hard to believe.
