Kitletics Review · 7.9 Solid

CLIF Bar Original is a energy chew (45 g carbs/serving; no caffeine). Dense energy bar (~250 kcal / ~45g carbs / ~10g protein typical Chocolate Chip label) — designed for lower-intensity long runs, ultras, and aid-station style fueling when a gel feels too thin and you can chew. I'd shortlist it for substantial calories for long, slower efforts. The trade-off is hard to chew at marathon race pace — PowerBar Energize is the cleaner compare when that is most of your week. It fits buyers who actually need a energy chew (45 g carbs/serving; no caffeine), not a one-product rotation.
