New MapMyRun link and calories different than MyFitnessPal

I've used MapMyRun in combination with MyFitnessPal for the last year+ with great success. I walk/run with the GPS on mapmyrun and then use the time and average pace (as close as I could find in myfitnesspal) to log my calories. Today I saw that they have the 2 apps linked and thought - wonderful! But, when I importated my workouts for the last month (so I could see them side by side) the calories are off by quite a bit. Which one is the most correct? For example, MyFitnessPal would show a lower calorie burn for the same minutes at the same or faster rate that the MapMyRun shows. It's typically off by 100 calories or so per 45 min. I'm maintaining and good with a little fluctuation, just wondering if anyone else had noticed this and if anyone knows which is more accurate. I don't have a heart rate monitor and have always just gone with the more conservative number in MFP.

    Have you updated your weight on MapMyRun since losing? If not then that might be why there are such differences.

    Hmm - no, I guess I didn't realize there was a place to put it on MapMyRun. I will go and look - thanks!

    I found it and you are right - hopefully it will adjust my calories now and I can sync them. I've lost 40 lbs so I would imagine it makes a difference! Thank you!
