But that's not right. It's not "just" for your sanity, like it's less important. That mental clarity is the whole point now, a real goal. It's just as valid as chasing a fast mile time, maybe more. The quiet time to sort your head out is the actual workout now.
Totally get what @pat540 means. The mental win became the whole point for me too. It's like the run flipped from training your body to training your brain lol.
