Play golf is mentally demanding
Very good question. I’ve never run a marathon, but I did run cross-country in High School.
They are both mentally demanding, but in different ways.
In running, you are having a mental battle with yourself. You body is telling you to quit, but your mind has to convince yourself to keep going, despite the pain.
In golf, the mental stress is to block out distractions.
I’ve done both distance running and golf, I think I was more mentally drained after a competitive round of golf.
marathon i think is more demanding because u got to keep your self going and keep yourself from going to fast or to slow
