Calculating burn from running

I have a watch with HRM built in. I get the HR every now and then along the route (in this case, a 10 mile run). I never see a number below 160 after the first minute and I have not seen any reading above 168. I am a 54 yo male, 170 pounds. When I use 160 for 100 minutes in a calculator, I get over 1700 gross and about 1600 net (I am 5' 9", which is also needed to calculate net). Does that seem right?

BTW, I used this calculator:

    That does sound a little on the high side for a 10 mile run, but if it's quite hilly it could be accurate. I would expect closer to 1300 given your stats.

    General rule of thumb I use for estimating (I stress, estimating), is 0.8 calories per mile per pound of body weight. That is based on something I once read in Runners World and does not account for my HR. MY HR is usually in the high 140s-low 150s for my long runs.

    Need your weight too. *cancel that I see your weight. Your calories burn seems high to me...

    I'm 44, 6'3, 215lbs. I ran 11miles today pretty easy pace just over 10.5 min miles. My HRM spit out 1556 calories. I didn't check, but I'm sure my HR was around 88-90% of max on average.

    Gross burn: 0.75 * body weight in pounds * miles run

    Net burn: 0.63 * body weight in pounds * miles run

    In your case, 10 miles @ 170 pounds yields 1275 gross calories.

    I am assuming you are getting your formulas from this article so I thought I would link it as well:
    http://m.runnersworld.com/weight-loss/how-many-calories-are-you-really-burning?page=single

    Of course the above formula is just an estimate and of course elevation, temp, HR etc play a role

    Regarding target HR, I thought this (an MFP friend shared it with me) might interest some people as well:

    Miles run without HR in calculations yield lower numbers. I should have mentioned that I knew that. That's why the HR calcs seem suspect. But they should be more accurate than the estimate based on miles run.
