I'm very interested in starting trail running. It's a lot of fun and I really enjoy it! I'm just curious what effect it will have on my body composition. I plan on keeping my heart rate below 75% of my max. My main concern is that it might spike cortisol and reduce my muscle mass in the long run! Should I be worried about this? I don't want it to have any detrimental effects. What are your thoughts?

Is trail running primal?
