You're in your fifties and you're running a sub 1:19 HM? Color me dubious on that one. Possible, but not likely.

Although you're right that it would be a piss-poor treadmill if it were built to max out at 8 minutes/mile pace or slower. I suspect none are, but I think the fellow reporting it was at heavy weight, so perhaps that affected things.

You caught me. 1:23, close enough for illustrative purposes. Besides, the age group record is 1:09, 1:19 isn’t that fast.

Ha, still not bad, kudos. 1:19 is further out on bell curve tail, enough to raise some doubt, at least on a geeky website . . . .

statistics shows there are indeed some runners in this age group which run 10k close to 6 minutes per mile and even faster:
