Honey stingers, both the gels and the chews, have become my go-to fuel.
They are Gluten Free, more natural than Gu (which I still use), and delicious.
I get both the gels and the chews. The gels seem to be better when I'm fading. The chews seem to be better when I feel hungry.
Supposedly a chocolate exists, but I haven't found it in the stores yet! I like vanilla the best.
Nutrition: Very high in sugar and have a few ingredients with long names, which I'm weary of but it's hard to avoid. Overall, though, much better than the alternatives. 100 to 160 calories per pack.
Taste: Really yummy! Since the ingredients are all natural, you don't get that awful syrupy artificial aftertaste.
Packaging: The gels are really easy to open. I had some trouble opening a pack of chews on the bike.
