Haha thanks man, I appreciate that. As I said before, I feel like I barely get anything done, but I appreciate what you said. Makes me feel a bit better!
Well, the gist is that many runners get caught up in what they call the "black hole" training zone - too fast to burn fat, but too slow to improve their cardiovascular system max.
So you reduce the pace by running at a much lower heart rate - Sisson cited 180 - your age as the target rate where you burn fat instead of sugar. And that means you can go longer, get leaner, and avoid sugar cravings because you're not hitting the anaerobic zone and depleting glycogen levels.
Read this, it explains it better:https://breakingmuscle. com/learn/easy-endurance-using-the-magic-180-rule.
I broke the link up with a space so I could post it here, so fix that and check it out.
So you basically alternate slower runs with hill sprints and regular sprints that work your anaerobic system, and this leads to more fat loss and less wear-and-tear on your body.
At least that's how I understand it. I could be terribly wrong. But it's worked for me, so I think I'm doing something right ....
