Yeah, I thought as much. Imagine walking from St. Petersburg to Vladivostok. I wonder how long that would take.
It's about 10.000 km. Average walking speed is 5 km an hour. If you walked for 5-6 hous each day (I doubt your feet could take any more), you'd need about a year!
In my southwestern Norwegian home province there is a folktale about a guy (Pilt-Ola Songesand from the famous
Lysefjord) who wanted to emigrate to America, but didn't want to pay the ship fare, so he walked through Scandinavia and Russia to the Bering Strait, where he changed his mind (or was again too cheap to pay the ferryman?) and walked back again! Reportedly he was away for 7 years. (It might just have been a tall tale inspired by him walking up to the North of Norway, to the Finnish / Russian border, to learn reindeer husbandry from the Sami people.)
BTW another verified Norwegian 19th-century long-distance pedestrian from deep fjord country was the runner Mensen Ernst, who in 1832 ran from Paris to Moscow (2500 km) in just 15 days. From Moscow he went in a post coach to St. Petersburg where he performed for Nikolay I and Alexandra Fyodorovna.
