Aside from the pros, cons, and specifics of all the examples cited in this thread, what's the common theme that runs through almost all of them?
Yes, there are a few exceptions, but:
The overwhelming majority of the races mentioned are not at all recent.
There are quite simply very few mid-distance, and almost no distance, runners with any real courage anymore. It's all just sit-and-kick. And it very often reaches the point of absurdity when a high caliber field in a big race goes out slower than your average high school race. Maybe they pick it up some in the middle, maybe not. But the "race" doesn't start until usually the last 800 to 400. It's a waste, not to mention a sad commentary.
And, as has been discussed here and elsewhere before, this is one of the more significant reasons why our sport doesn't appeal more to a broad audience. As I've heard many times, what's the point of running or watching a 1500 or mile race, much less a 5000 or 10,000, that goes out idiotically slow and doesn't really become a race until the last 400 meters?
