Energy bars have come a long way from the rock-hard, hardly-digestible caloric bricks they used to be.
I still find myself reaching for real food rather than "science food" also known as prepackaged bars and chews most of the time.

I've become pretty good at making my own homemade no-bake energy balls. The Scratch bacon maple almond butter rice cakes are another favorite. They have become my go-to for endurance events such as Unbound and other endurance mountain and gravel events.

That said, there's something to be said for the convenience and shelf life of store-bought energy bars. Any fellow mountain bikers have recommendations on their favorite off-the-shelf snacks to eat while riding?
