    Ok, so again I am currently training for a marathon in Oct. and am up to over 14 miles on the weekend and approx. 12-20 additional miles during the week. I weight approx. 150, am 5'7 and have an office job. How many calories should I eat a day, and how many do I eat on my long run days?

    Thanks

    Granted I'm older and (maybe) slower but for my 10 mile run Saturday my heart rate monitor said I burned 867 calories. Using the calculation that was posted (.65 x weight x miles) it came up to 913 - pretty close in my book. MFP says I burned 1032.. Personally if I was just going by MFP numbers I'd only eat back (up to) 1/2 the calories it says I burned and I'd keep a close eye on the scale just to verify it.
