means A long, arduous journey made on foot or under your own steam, usually over rough or remote terrain.

from From Afrikaans and Dutch 'trek,' meaning to pull or draw — the same root as English 'trick' in the sense of a pulling motion. It entered English in the 19th century via South Africa, where Dutch-descended settlers spoke of the 'Groot Trek,' the great overland migration in which whole families literally drew their ox-wagons across the veld. So the word still carries the ache of hauling yourself somewhere by sheer effort.
