Sudden Stop Runner Ass

This ass is cruising along beautifully until, without warning, the map shows a hard stop, a little dot frozen in place, a mystery for the ages. What happened there? The GPS says they simply halted. The heart-rate graph says something spiked, badly, in that exact same moment. A dog, a hill, a phone call, a sudden confrontation with mortality at the mailbox, we will never know, and they will never tell. The run resumes as though nothing occurred. But the data remembers the pause, and the spike, and the truth. A runner with one unexplained full stop per outing and a firm, permanent, non-negotiable policy of not discussing it.
