Her average for that week is 13:36 per mile (check my math). Today's morning run was 4.16 mph or 14:25 per mile and this afternoon she's at 3.70 mph or 16:13 per mile. She has slowed but it could just be a temporary blip.
OMG she has slowed 49 seconds per mile over the course of a few weeks of 50-60 miles per day! Must be a scam! And if she slows 70 seconds on a particular run, it's "All over Rover!"
There is this thing called, oh what is it, oh yeah: "fatigue". It is a characteristic of humans. You might look it up.
Conflating 13 with 14-minute miles (which may prove not to be the case anyway, it is only Thursday) and "11.5 vs. 15 minute miles" is the out-and-out bullcrap. If she had been averaging 11s and now was doing 15s, yeah, I would wonder what's up.
