In contrast to other comments on this thread, I really enjoy running to music - yes really. If you get a nice crisp early morning in the countryside / by the sea / in the mountains with some music on, an hours run completely resets my view on life.
I am also a (very bad) drummer which again gives me an opportunity to focus on nothing else other than the music and vaguely trying to maintain a rhythm. Much to my drum teachers amusement my heart rate is higher drumming than it is running which gives me the added benefit of keeping fit while I play.
