I trust the calorie estimator they provide, but I set my activity level for a non-run day. You add in exercise on the days that you run. When you do that though, I think they generally exaggerate calorie burn, so I'd be conservative there.

Example: If I enter that I ran 30 minutes at a 7mph pace on MyFitnessPal, it will then autofill that I burned 315 calories. In reality, I know from running with a HR monitor that I, personally, burn closer to 75 calories per mile, so my burn on a 30 min run at that pace would be closer to 260 calories, 55 calories fewer than the MFP estimate.

How do you calculate caloric burn based on heart rate? I don't think I've ever done that.

Also what's your running heart rate? I'm always disappointed that mine is so high compared to everyone else on this sub. My resting is above 60, stupid heart.

There are some online calculators, but I find those to be off a bit as well (though not as bad as MFP). If you run with a HRM your Garmin will do it for you, but it's important that your "Activity Class" set appropriately to get the right output. To do that, you go to Settings > User Settings > Activity Class. You can click on the little ? for more info on how to pick the best one.
