I usually wear glasses so when I run in high humidity including rain, like today, my glasses fog up and my view of the world goes wet and milky. I think the clouding of my vision turns my thoughts even more inward than usual. Runners zone out or get into a zone as the miles click by and the rain seems to accentuate that. Soon all that exists is the wooshing sound of my breath as the pavement flashes by (well, rolls by, I’m not that fast…yet). I don’t write while I’m running, not exactly, but I do find my thoughts wandering to a character, especially one that I’ve placed in a life or death situation. No doubt the rushing of blood, the increased heart rate, sweat, exertion and the simple act of motion contribute.
