Maybe you've run in a marathon, lost yourself on purpose and subsumed your own individuated struggle in a sea of it and rolled. Or maybe you've just been on the sidewalk as a marathon flows by, which is by itself about as intense a sports-watching experience as is available here on earth. The sheer volume of emotion that pours through the average marathon is unlike anything else; the awe it evokes is unlike anything else.
This can be found not just in the unflagging mastery of the people at the front, although there's also that, but more and maybe more purely in the various pursuits of the various runners, every one chasing a different thing, each fighting their own armageddons in their burning legs, every race run differently and for different reasons, every race run against the same human limits, and in defiance of them. Everyone fights everything, alone and together. There is nothing like it.
Except for this massive duck stampede, in Thailand. This massive duck stampede is a lot like a marathon, actually. The ruling is: sports.
