I've been watching past seasons of International Versions of TAR and then I wonder, when a team checks-in are they required to bring their bags with them (except the fanny pack which I know they should always bring). I'm thinking the big, bulky, backpacks. I remember seeing teams leaving their bags when running to the mat and there are some that won't drop it even if it's a footrace. And in one leg of TAR: Australia Season 1, it was a footrace for first place, and the team members scrambled to get their backpacks on their pick-up trucks before they ran.
So what is the rule on this?
