Maurten Gel 100 Energy Gel

Maurten has become the nutrition choice of elite endurance athletes including Tour de France winners. The hydrogel technology encapsulates carbohydrates in a way that minimises GI distress even at high intensities. The gels are unflavoured, which many athletes prefer after hours of sweet flavours. Expensive but genuinely effective at the highest intensities when performance matters most.

High5 Energy Bar Variety Pack

High5 produces a range of cycling nutrition products and their energy bars are a staple for UK cyclists. Real food texture makes them more palatable than gels during low-intensity periods and the 40g of carbohydrate per bar provides substantial fuel. The variety pack lets you identify your preferred flavours before committing to larger quantities. A practical choice for long sportives and touring rides.

Precision Hydration PH 1000 Electrolyte Tablets

Precision Hydration was founded by a sports scientist who studied sweat sodium rates and their products reflect this expertise. The PH 1000 tablets provide the right sodium concentration for moderate-to-high sweat rates and dissolve quickly in water bottles. Proper hydration with electrolytes prevents the cramping and cognitive decline that can derail long rides.

Veloforte Natural Energy Bars

Veloforte makes genuinely tasty cycling nutrition using real food ingredients rather than synthetic flavours. The bars use dates, fruit and nuts to provide sustained carbohydrate energy without the processed taste of many alternatives. UK-made and popular with cyclists who want nutrition that feels like food rather than medicine. An excellent choice for long, low-to-moderate intensity rides.

Buying Guide

The 60-gram carbohydrate per hour rule applies to moderate efforts. Hard efforts can utilise up to 90g per hour but require a mix of glucose and fructose sources for optimal absorption.

Train your gut as well as your legs. Consuming nutrition at race intensity takes practice. Train with the products you plan to use in events — introducing new foods on race day is a recipe for GI problems.

Start fuelling from the first 30 minutes of a ride, not when you feel hungry. Hunger is a late signal. Proactive fuelling maintains performance; reactive fuelling always feels like catching up.

Hydration and nutrition are linked. Electrolyte solutions help maintain sodium balance during prolonged sweating. Plain water is adequate for rides under an hour; electrolytes matter increasingly as duration increases.

Real food works well for long, low-intensity touring days. Save high-tech gels for high-intensity efforts when digestion is compromised. Sandwiches, bananas and flapjack serve touring cyclists very well.

Final Thoughts

SiS and High5 are the most widely available and best value cycling nutrition brands in the UK. For elite performance situations, Maurten gels offer something genuinely different. Experiment with different products on training rides to find what your stomach tolerates and what your palate enjoys.
