Whenever running or exercise comes up in conversation, someone will invariably ask what music I listen to. They're often shocked when I reply that I don't carry anything on me other than a dumb stopwatch and my keys. Running is the only respite I have from being wired in, a sort of pre-shower shower time for me to face myself and my ideas. I've been trying to make it a habit to immediately jot down any ideas right after.
