Overview
What makes CLIF Bloks Sours different from standard Bloks?
CLIF Bloks Sours Energy Chews are the same bite-sized carbohydrate cube format as classic Bloks, designed specifically to solve a real problem on long rides: flavor fatigue. When you have been fueling with sweet chews or gels for two or more hours, a pronounced sour profile cuts through the sweetness, keeps your palate engaged, and as an added bonus tends to prompt you to drink more water, which has no downside. CLIF developed the Sours line in 2024 in collaboration with their athlete community specifically for this purpose. Available in two flavors: Sour Green Apple (caffeine-free) and Sour Strawberry Lemonade (25mg caffeine per serving via green tea extract).
Each packet contains 6 cubes. Serving size is 3 cubes, delivering approximately 21g of carbohydrates and 107mg of sodium per serving: slightly lower in calories and carbs than standard Bloks, with a bit more sodium per serving. Non-GMO, plant-based, no high-fructose corn syrup, no artificial flavors. Gluten-free. Always consume with water. The individual packet is the right format for testing these out before committing to a box.
