If you've ever run a marathon, you'd know. 4 hours is still a pretty decent time for 26 miles and, for most runners, the last leg up to finish line is usually a pretty exhausting/euphoric time. Aside from your own heartbeat and breathing, you really don't notice much else.

To me, it looks like they respond physically to the shockwave but are not mentally registering anything other than the finish line.

Agree, that close to the finish line I would have done the same. Especially as everyone would be pushing so hard because it's Boston.
