US calorie calculator

[gej]

I stumbled across the calorie calculator at http://www.runnersworld.com/tools/ca...ned-calculator

"built specifically for running"

My weight (70kg) is "below the minimum supported by this tool"

Says something about the American origin of the tool?

just tested this and the minimum it will accept is 80kg = 12.5 stone!!!

I notice there's no provision for ascent. Obviously we all run on the flat only!

It works in pounds

[Dave_Mole]

it does!
how odd: goes down to 80lb (= 36kg/5.7 stone) but only if you select lb....

Not odd at all. That's how the Sherman Tanks work. You've surely seen the movies? "..... he was a big guy, 6ft 4 and about 230lbs."

Interesting result though. I entered my run to/from work which is a very urban slightly hilly 5 miles spot on. My weight (sadly) does not vary to any real extent and I have been doing the run for nearly 2 years. The calculator says 567 Cals but my trusty Polar HRM consistently states circa 340 Cals. I know that both use industry standard algorithms but that level of difference over so short a distance makes me doubt the accuracy of either.

I was also surprised by the estimation of calories used. It's over 100 calories per 8-minute flat mile for someone weighing 135lbs. That seems way too high to me.

I got that when I put the time in as 38 rather than 38:00 - apparently I burned 105 calories per mile for 5 miles yesterday. Although if you change the time, the calories burned stays the same???
