So I am reading this book in my english class, and I'm confused as to what trails did, Zaroff, Ivan And Rainsford take? Please Help

Rainford realized that running around aimlessly was not going to help his plight. Instead, he decides to leave a trail consisting of loops and spins. Afterwards, he climbs a large tree to make himself comfortable for the night. Rainsford is confident than Zaroff will be unable to follow him to his current position. Despite his attempts at self assurance, Rainsford is unable to sleep that night. They basically run through swamp trails and a trail to a cliff near the end of the hunt.
