Probably one of the biggest choices I have to make in preparing for the GORUCK Challenge is which backpack to use. One of the conditions of the event is that you must carry 4 bricks with you for the entire challenge, among other requisite and recommended gear. Oh wait, make that 6 bricks if you weigh over 150 pounds (because life isn’t fair).
Since the GORUCK Challenge originated as a way for GORUCK to test their gear. They primarily make military inspired/tested backpacks and accessories. They are a bit expensive, and probably won’t appeal to the flashy, techno-cool crowd ( from which I can’t completely disassociate myself), but they do appear as literally bomb-proof as conceivable. The recommended pack for the GORUCK Challenge, and claimed most versatile, is the GR1. At 26 liters, it’s their mid-sized pack and original creation. But my question is, is it overkill? Can I use something that I already own, or find something a bit less expensive that will do the needful?

Seriously, don’t try and carry 6 bricks in anything made by Osprey. I blew out the seams on a Manta and a Talon pack before realising they weren’t up to the job i was asking of them… and that was only mountain biking and commuting!
Since bought a GR1 and am delighted. True confidence in your kit is an important part of making yourself feel badass enough to do things like the GORUCK challenge!
