Totally this. I've recently embarked on a weight loss/fitness journey (coming up on 50 rotations around the sun) and I find it incredibly helpful to think of the 250 calorie chocolate bar as roughly 25 minutes on the treadmill.

Burning a thousand calories an hour on a treadmill is kind of high, isn't it? Like, you'd have to be pushing really hard for the entire hour to hit a thousand calories, wouldn't you?

Brief search says us male is 200lb on avg, 200lb male burns just over 1000 in an hour at 8mph, average adult 10 mile is 1:17. Soo, 8 miles in an hour is 7:30 miles...10 in 1:17 is 7:42.

Closer than I thought, I suppose, but definitely requires above average pace (where the average is times recorded by runninglevel.com)
