I believe that humans are optimally designed for stamina in low-level cardio, i.e. ability to cover large distances mostly at walking pace or a slow running pace. Our ability to sprint cf most other mammals is pretty woeful.
I'm sure that Paleo humans evolved this stamina not only for tracking prey, but also for gathering materials required for making tools and agriculture, plus for communication, general intelligence and information gathering. Mobility can confer a diverse range of benefits when it's not all about outrunning predators or catching prey.
Ability to cover huge distances to collect water, which required a high degree of intelligence and communication, enabled Paleo humans to achieve top-carnivore status in most desert environments.
