Rucking is covering ground on foot under a weighted pack — borrowed from the military and turned into everything from timed solo challenges to long team events. Simple to start, deceptively hard to finish.
It rewards steady effort and mental grit over speed, and the community side — moving together under load — is a big part of the draw.
Covering a distance on foot under a weighted rucksack — from timed solo challenges to longer team events.
