Yep!
Carb loading literally means to load on carbs haha
2-3 days before your long run, increase carb intake to around 4-5 grams per pound of bodyweight per day. So if, for example, you weight 150 lbs, that's 600-750 grams of carbs per day.
Aim for easily digestible foods that aren't very heavy in fiber, such as pasta, rice, breads and potatoes.
