Fitbit Calories - HELP!

Options
Hello. I ran 20k today at approx 7.21 per K running for 2hrs 34 mins total.
MapMyRun/MFP give me 1401 calories for this. However Fitbit says I only earned 994 calories. So which is right?
I am female, age 36, 5ft 1.3 and weigh 9stone4
Such a huge variation and the difference between having some more cake or not so I would love to know. Why so different ? Who to trust ?
Thanks
Kelly

    Is your fitbit using heart rate? If so, I'd go with that.

    If not, I'd take the lower of the two.

    No. It's not using. It's just a flex. So Fitbit gives me the lower reading. Boo. No more cake!
