Is this sentence understandable?
a continuous 20000 km-long chain of encounters (or "people")
in french that would be :
Une chaine interrompue de rencontre sur 20 000 km.
("Chaine" in this context means a continuous string of events linked to each others. Each encounter would be a link of this long chain), (or "string?).
I need this sentence to present a social experiment that consist of encountering people during a 20000 km walk. The idea is to show a continuity of the chain : a "chain" of encounters (a lot of people and culture) from the beginning to the end. Chain is in itself continuous but the mean idea is to highlight the continuity (it could have been several little chains)
