110k is neurotic. Distance runners are often neurotic, they run for the runners high, they run as an antidepressant, they run to burn calories because they eat too much to deal with life stresses, they run to escape loneliness, they run to make themselves healthy so they'll be more attractive to potential mates, they run to get time away from their family, they run to replace other addictions they're running away from, I've experienced it all and I've seen it all.
