22:46/172

Something does not add up.

At 88% average heart rate compared to my max., I ran at roughly my expected marathon pace. That should put me just above the top of the endurance zone. In other words, less than 83% if I believe Greg McMillan. Unless my real max. heart rate is 208 and I have the heart of a 12-year-old boy.

Maybe I should go check my time for a hard run at the track one of these days. Theoretically I should be able to extrapolate even from a 5k.
