> 7 min/mile, or 100 m in 25 seconds seems doable if you excercise regularly ...
I have to disagree. I run 20 miles per week at about 11 min/mile yet could not run a single 7-minute mile to save my life. The best I can do at a "max effort" is a single 9-minute mile. Never even a 100-yard stretch in the 8s.
But then, I'm 77 years old.
Nowhere in this discussion have I seen an accounting for age. Perhaps with advancing age walking is more efficient (whatever the metric) regardless. Anecdotally (I see that word used here a lot <g>) I don't see any other runners my age, only walkers, so that must be true.

In 1972-74 when I was a Minuteman I launch officer (DMCCC) our 10 missiles were /always/ on alert. You would expect to see 10 green "Strategic Alert" lights across the crew commander's (MCCC's) console unless something was wrong (requiring maintenance or a brief calibration).
IIRC we were in a perpetual state of DEFCON 4 in those days.
