Power your pedal strokes with Gu—the sports fuel that keeps you moving, feeling good and enjoying every kilometre. It mixes science, flavour and real endurance so you’re ready for every training ride, group spin or long adventure.

Gu Energy Labs was founded in 1994 by Bill Vaughan, after developing his first energy gel prototype in 1990. Its origins lie in meeting the specific nutrition needs of endurance athletes—and in 1996 it already supplied gels at the Ironman World Championship. Today Gu is still athlete focused and driven by science.

Your ride benefits because that history means trusted blends of carbohydrates, electrolytes and amino acids, all designed to support energy, hydration and recovery in real cycling conditions—not just lab ideal scenarios.

• Gu Nutrition

• Precise fuel blends designed by scientists using maltodextrin and fructose so your energy curve stays steady when your ride gets long or intense.
• Electrolytes and amino acids included in many products to support hydration, reduce muscle soreness and preserve performance over many hours in the saddle.
• Caffeine options you control—some flavours have 20 or 40 milligrams for a boost when you need it, others are caffeine-free so you can match your tolerance and timing.
• Proven ultra-endurance pedigree built from real competition experience, then scaled to everyday riders so your mid-week hills and weekend adventures benefit from pro grade nutrition reliability.
