The Science in Sport (SiS) Energy Oat Bar brings a highly technical, science-backed approach to solid endurance nutrition. Moving away from standard high-sugar confectioneries that cause dramatic glucose spikes, this macro-balanced 70g bar relies on a wholesome base of 36% rolled whole oats and structured oat syrups. This formula delivers a steady, low-glycemic index release of 40g of complex carbohydrates, keeping your muscle glycogen levels topped up over hours of continuous physical output while preventing the dreaded mid-ride "bonk."
What truly sets the Energy Oat Bar apart from traditional cycling snacks is its dual-action recovery integration. Fortified with 10g of premium plant protein derived from a clean soy and pea isolate blend, it actively feeds working muscles during prolonged training blocks to protect against lean muscle breakdown. The texture is engineered specifically for athletes: it chews cleanly and effortlessly without turning pasty or sticking to the roof of your mouth, even when your hydration levels are low. Independently batch-tested and Informed Sport certified to ensure freedom from WADA-banned substances, it functions perfectly as a pre-ride carbohydrate loading block, a mid-ride fuel source for long-distance base miles, or a satisfying, muscle-repairing everyday snack.

✅ Why This IS For You
Long-Distance Base Miles: The 40g of slow-burning oats provides the ideal steady energy curve for long, steady endurance rides or multi-hour gravel bike packing routes.
Pre-Race Carbo-Loaders: Perfect to consume roughly 30 to 60 minutes before rolling out of the starting gate to smoothly prime your glycogen reserves without upsetting your stomach.
Busy, On-The-Go Athletes: Functions beautifully as a satisfying, high-protein lifestyle snack between work tasks, ensuring your daily macronutrient bases are completely covered.
Riders Over Gels: A fantastic choice for endurance cyclists who experience gastrointestinal distress from syrupy, concentrated energy liquids and prefer real, solid food.
Clean-Sport Competitors: Essential for club and elite racers who require strict, certified batch-testing documentation to eliminate any risk of accidental contamination.
❌ Why This May NOT Be For You
High-Intensity Criterium Racers: During anaerobic, red-lined racing efforts, the body requires instantaneous simple sugars; a fast-absorbing SiS Isotonic gel is much more appropriate.
Strict Gluten-Free Diets: Because the recipe utilizes traditional wholesome rolled oats, this bar is not suitable for individuals with celiac disease or severe gluten sensitivities.
Jersey Pocket Minimalists: Weighing in at 70g, it is physically bulkier than standard 40g mini bars, meaning a full box will require a dedicated frame bag or spacious storage layout.
BFC Pro Tip
If you plan on eating this bar during a long ride, partially tear open the wrapper from the top down to the middle before you place it into your cycling jersey. Because the 70g oat structure is thick and satisfyingly dense, trying to tear open the heavy foil with your teeth while managing technical handling or crosswinds can be clumsy—pre-gapping the foil allows you to effortlessly slide the bar up like a push-pop with one hand!
