If you like running, then do it. No one is telling you not to run. It's just important that you know the health implications. If the joy and satisfaction you get from running is greater than the increased risk of injury, muscle catabolism and joint health, then run. The issue Primal has with chronic cardio is that people think it's healthy, so they do loads of it even though they hate it. If you love it and understand the risks, that is a totally different situation. Think of running like whole wheat pasta. Most people buy whole wheat pasta because they think it's good for them, and you just have to have those servings of whole grains. We know that not to be true. However, if you know the health implications of whole wheat pasta but you just love the stuff and indulge every now and again, then that's a totally different story. It's all about risk vs reward. Know your risk, and if the reward outweighs it, go for it!
