Your body goes into an autopilot trance. It's happened to me on long bike marathons where as long as your water, electrolytes and fuels are still coming in your brain is in this primal mode where your body knows what to do, and your brain shuts off. You will hear conversations in memories vividly, or the 'singing' of the frame of the bicycle and its connection with the pavement through your tires becomes readily apparent.
Later Hominids are meant for this. Without being able to pass long time chasing our prey to the moment of its exhaustion, we'd not have been able to secure the cholesterol needed to further evolve our brains.
"exhaustion chase" never lasted that long, I don't remember the times exactly but animals that don't sweat are exhausted pretty quickly, a couple hours at most.
Doesn't make any sense to me either. Not a biologist, but AFAIK animals known for being sprinters are able to outperform you in bursts, with refractory periods of extreme exhaustion and vulnerability. Especially if already wounded. You turn the chase into a game of hide-and-seek.
Small fish/shrimp can appear to "teleport" since they dart away so quickly, but if you harass them enough, you exhaust them into a state of shock. It's no longer a chase, it's a harvest.
Even in manhunting, you get nowhere chasing the subject since you move at the same speed and the element of uncertainty tilts in their favor. So you try to anticipate where they're going and ambush them there. You turn the chase into a trap.
We're apex predators for a reason. Exhaustion chases don't make sense.
