Long distance running is also called endurance running which usually is 5 miles or longer. I used to love running.
I never liked running, I was more of a sprinter, what can you tell me about that
I don't know much about sprinting. Always been into running which is greatly aerobic but also takes mental strength.
Yeah maybe that was why I was so bad at running I only have 10% of my lung function
Sorry  to hear that. I find it interesting humans are the best at running long distances among all the primates. 
I find that kind of hard to believe, how can that be?
The hypothesis on long distance running believe it arose due to better scavenging and hunting in larger areas, so we adapted 
Is it because we had to out run dinosaurs...
Not that I know of. Either way it's great for our health especially cardiovascular health
