First, I can't believe this thread is still going.
Second, thanks for the video clip.
Third, ARE YOU FUCKING KIDDING ME? It was (decidedly) incidental contact by someone who was protecting himself from a person blundering in his path.
If the guy was finishing a half-triathlon, I can easily understand his inability to shift direction on a dime. This reminds me of Derek Clayton, a rawther heavy trainer, who once ran into a tree. His quote was something like, "Yes, I saw it--I just couldn't get out of its way!"
Similarly, when Gerry Lindgren was training for the 1972 OT, he allegedly was up to 50 miles/day at one point. (Though I suspect those were "Gerry miles.") And he injured himself by running into a car.
Parked.
His own.
When a *competitive* athlete (rather than a simple "participant") is in the last stages of a hard run, the kind of agility people are suggesting is out of the question. Watch where you're going, lady, and stay out of the competitors' way!
A DQ based on the clip I watched is an absolute injustice. And here I thought *my* generation (Baby Boomers) were the biggest whiners in the world. Well done, lady, ya outdid us!
