Clif Bloks Energy Chews

You're 90 minutes into a long ride and your legs are fading. You need carbs — fast — but gels aren't your thing and real food is a mess to manage at pace. Clif Bloks solved that problem back in 2005 and have been a staple in jersey pockets ever since.

These are the energy chews that raised the bar on what a chew could do. Not just fast-absorbing carbohydrates, but a meaningful dose of electrolytes — the minerals that keep your muscles firing and fluids in balance — built right into every cube.

Precise and Portable Each sleeve contains 6 bloks, with every serving of 3 bloks delivering 24 grams of carbohydrates. That measured format makes it easy to dial in exactly how much fuel you're taking in and easy to count out how many sleeves you need for a long effort.

Built for Customization Not all efforts are equal, and Clif Bloks are designed with that in mind. Caffeinated flavors — Black Cherry (50 mg), Orange (25 mg), and Tropical Punch (25 mg) — give you an added boost when you need to push. High-sodium flavors like Margarita and Salted Watermelon contain 3x the sodium of standard flavors, making them the go-to for hot days, humid races, or athletes who tend to be heavy sweaters.

Plant-Based and Made to Move Made with organic tapioca syrup, no high-fructose corn syrup, and no artificial flavors — Non-GMO and plant-based. The soft, not-too-sticky texture makes them easy to chew and swallow mid-effort without slowing you down.

How to Clif Bloks

Start fueling before you actually need it. Eat half a sleeve 15 minutes before your session to top off your glycogen stores, then continue with 3 bloks (half a sleeve) every 20–30 minutes throughout any effort lasting longer than an hour.

Always chase them with water — the carbohydrates absorb more efficiently with adequate hydration. If you have a sensitive stomach, start with 1–2 bloks at a time and work up from there. The slim, easy-open packaging slips right into a jersey pocket or running vest, no fumbling, no mess.

Clif Bloks are trusted by runners, cyclists, triathletes, and adventure athletes worldwide for good reason. Simple ingredients, real results, and a format that actually works when you're moving fast.

Stop settling for fuel that's hard to use mid-effort. This is the chew that belongs in your pocket on every long day out.
