Macro adjustments for marathon training

I'm marathon training. I did a long run Sunday and added 50 grams of carbs per hour of running. I had another hour long run today and am really hungry! Should I add another 50 carbs since I ran an hour? Fitbit says I burnt 933 calories. I know last challenge you said to only do this once a week.....

Sure, add in another 50 grams of carbs if you’re hungry! We don’t really go by apple watches or how much they say you burn. They’re not always reliable and vary a lot depending on which device!
