What to Know Before Running a Marathon
12 Things I Really Wish I Knew Before Running My First Marathon

I've lost weight from training for a marathon in the past, but I was also meticulously tracking every bite of food that I ate (and would run extra if I wanted to eat more).
I used the Nike Running App or MyFitnessPal during my marathon training, and while both are great apps, they can differ by a few hundred calories when estimating what you've burned. It's super easy to overestimate how much you're burning and underestimate how much you're eating, so it's important to be mindful.
