Factual error: Charles and Robert manage to outrun a charging Alaskan brown bear over a course of several hundred meters, leading it into a trap. This is absurd. The absolute maximum running speed of a human being is about 27 kilometers an hour, and that is for an appropriately dressed, fit athlete over a very short course on flat ground. They are in a rock strewn stream and are wearing heavy winter clothes. A fit, healthy, active male Alaskan brown bear like the one chasing them could hit 45 kmh in that environment without popping a sweat and could keep that up for a kilometer or more. When enraged or charging prey - as this one was - they have been clocked at 56kmh. This is nothing to do with an adrenaline rush - that will not enable Charles or Robert to exceed their body's maximum running speed by 200%.
Factual error: While Anthony and the two others are staring at the bear as it screams, you see a large cold-blooded lizard scuffle up the tree right behind the bear's head when the young man says, "C'mon, let go!" No way that would live in the area they're supposedly in. (00:44:35)
Chosen answer: Under extreme and dire circumstances, the body can produce excessive amounts of adrenalin, enabling a person to ignore pain and perform physical feats they would ordinarily be unable to do.
