Yup. Let's discuss some details as the date approaches...
Currently, I am only training for the half marathon, so I am closely watching what I am eating (I am on Weight Watchers) and running. The benefit of Weight Watchers is that they give you extra points for working out and I track everything online so it's cheap and easy. However, I do agree that it does get VERY difficult to diet while training hard. When I am training for a marathon (I've done 2) or a longer distance triathlon, then I don't limit myself. I cut out a lot of foods that my body doesn't agree with like fast food and pop, but I still eat pretty much what I want because I am burning so many calories. Basically, I would recommend keeping a good balance of food intake, watch your portions, drink PLENTY of water, and try to eat a little slower. Remember that you can't be on a low-carb diet because as an endurance athlete your body needs the carbs. Sorry for the long winded answer. I hope it helps, but to sum it all up - I haven't exactly figured it out yet either!!!
