Plural of backtracker; multiple people or things that backtrack or retrace their paths.
From 'backtracker' + '-s' (Old English plural suffix). Standard pluralization of the agent noun.
In hiking culture, 'backtrackers' would describe hikers who reversed course—interestingly, this is now often replaced with 'turnarounds' because hikers view turning back not as retracing but as a strategic hiking decision.
