Calorie intake while training for half marathon
I just finished my first half marathon last weekend. I'm going to continue running them, and I really enjoy running. The issue I run into is that I have no idea how many calories I should be consuming. On my weekly runs I usually burn about 500 calories, but on my long run day (Sunday) I burn anywhere from 1000-1600 calories depending how far I go. I tend to give myself free reign on sunday to eat what I want, but maybe that is sabotaging me? Should I be sticking to 1500 calories or increasing my intake to 2500 to compensate for the hard workout. I work out a fair amount between running and lifting, but I struggle to figure out how much I should be eating. I lost about 50 pounds a few years back, and since then I eat pretty healthy. Mostly clean eating, very little processed food. But for the past year I've been packing on the pounds and I don't know why. I'm trying to get the weight off but I feel stuck. Any suggestions?
