Rucking is marching with a loaded rucksack (military speak for backpack). The ruck march is an essential of military training – but civilians can take part in GORUCK fitness events as well.
What are the essentials for rucking?
Basically you need boots (or shoes) and a rucksack for the weight.
Everything else beyond that is optional, but if you are going to get serious about it there is a lot of other rucking gear that can help.
