Then ran 2 miles in an hour and burned 100 calories per mile. But burned 200 in the hour. So.. er time is the important factor. I think. But I don't know. figures totally made up

DeeGee Feb 2012 10:21pm, 18 Feb 2012 11,047 posts	0 DeeGee Garmin does work on distance, but if it's anything like mine it also takes weight into account, and thus a meatier unit will burn more calories than someone like yourself! I think that 3250 for a marathon's a fair estimate actually. Other calculators would give me 1000 calories an hour.
DeeGee Feb 2012 10:23pm, 18 Feb 2012 11,048 posts	0 DeeGee I'm sure my 305 altered the calorie count according to Heart Rate. Does it not? Am I making things up now?

firemannotsam Feb 2012 8:31am, 19 Feb 2012 2,031 posts	0 firemannotsam Its a simple calculation. It takes a certain amount of energy to move a weight (you) a certain distance. So if you run one mile and weigh 10st it will take x calories to do that.
Robbo62 Feb 2012 9:17am, 19 Feb 2012 2,005 posts	0 Robbo62 surely the amount of calories burned would depend on the individual size of the person, just come back from a 9 miler and Garmin says 1116 calories so DGs estimate would be close for me ( 11st 6 ), but some one much bigger or smaller could be quite different.
KinkyS Feb 2012 11:06am, 19 Feb 2012 16,605 posts	0 KinkyS That formula gives me about 80 cal per mile, which sounds about right I suppose. My Garmin calculates calories by heart rate when I wear the monitor, and I burn more calories per mile the slower I run according to that. It comes out with about 60-70 calories per mile at 5k pace, and more like 90 per mile at recovery plod pace. Something to do with time and efficiency I guess?
Binks Feb 2012 11:20am, 19 Feb 2012 5,195 posts	0 Binks Yes time does not come into it except that if you run really fast then you'll burn slightly more when you have stopped. Not much though. I always went by a 75kg man will burn 100 cals per mile. More if fatter More if on trail More on Hills More in extremes of temperature More if you run like these http://www.youtube.com/watch?v=nGojEyYBmwc&list=LLZsxTBbw6YWF0nwliTvEEbw&index=22&feature=plpp_video
