80/20 Running

I am liking the concept of 80/20 running. 80% of the runs are easy runs at below ventilatory threshold. The other 20% could be high intensity or speed work. The pace at which you could carry on a conversation which may be around 30 seconds slower per mile than race times. Apparently most professional runners train this way.. someone studied the training habits. However they found most recreational runners do moderate training and probably have a 50/50 ratio of easy to heard

I have found it hard to listen to audiobooks or podcasts while running, but am wondering if my concentration issues could be intensity based. On some of these slower runs i seem to be able to focus and listen more.

I also found it interesting that according to a podcast I listened to.. the Rock runs first in the morning .. then he eats and later lifts. He is notorious for waking up at 4 am.

Does Jocko Willink run? I haven’t heard him mention it much, but like Goggins i am sure he did alot of it during Seals training.
