Middle Earth here...

I don't use power bars and energy bars... for one thing they are toooo chewy, and for another they are way too expensive...

I buy muesli style bars for kids lunchboxes... the best I have found to eat WHILE riding (that is, not pulling over to side of road to eat which I don't do) are the "Mother Earth" brand - Baked Fruit Sticks (apple) or Fruit Bars (apricot). They are soft and not chewy and moist enough not to get stuck in the throat as you chew and swallow while riding.

However, that being said my longest rides sit just under two hours... I'm not an enduro rider.

When my son and partner go out for their Sunday ride which is typically between 120 and 180km, they tend to take a selection of muesli bars, bananas and leppin satchets...
