On the hunger training front--I tried a Hammer Nutrition bar on my 60 mile ride today. It was mighty tasty, but I was shocked to see it had 11 grams of fat! So much more than a Larabar (12 g) and so so so much more than a Cliff Bar (5 g). And check this out--a whopping 44 g of carbs for the Cliff bar, but only 23 for Larabar and 27 for Hammer. So glad I looked--Cliff bar comes out way ahead!
