Yes it is, although one could probably find a similar attitude among other types of athletes. Perhaps because it's not a team sport, running seems to encourage in some people a nearly pathological self-centeredness.
More than a few are like that. There is some kind of exhibitionism, also.
A few weekends ago I took the girls to Portland, OR. On the way we stopped at Multnomah Falls, a tall waterfall with a visitor's center just off the highway.
Many tourists get their first good view of the falls when they emerge from the under-highway pedestrian walkway (tunnel). There it is, the waterfall, right in front of you.
Well, this idiot runner/hyperfitness/triathalon type guy was hanging from the rafter of the underpass right at the exit, doing pullups and blocking the view. He was dressed in the show-all spandex panties or whatever they were and no doubt a Portland liberal. His porpoising profile is the main thing you saw at that point.
But the show wasn't over. After completing the exhibition at the tunnel he then proceeded to do stair runs up and down the very same stairs the tourists use to get to the viewing platforms for the waterfall. It went on and on, past these old ladies with canes and assorted other visitors who will never be running up or down stairs.
There must be 599 million other places, even nice, pleasant ones, within 50 miles of Portland where this jerk could have done his routine. But no, he picked the tourist gateway.
