Why truefuels fits RSG
The useful part of this range is separation. The gel gives a known 40g carbohydrate dose. The electrolyte sachet adds sodium and minerals with 1g carbohydrate. CoreCtrl belongs before a hot event, not in the same mental bucket as race fuel.
That makes it easier to build, test and adjust the full system without accidentally double-counting fuel or assuming every product solves the same problem.
Practise the complete carbohydrate, fluid and sodium plan in training.
Both gels provide 40g carbohydrate. Low Salt contains 98mg sodium; High Salt contains 386mg. Choose in the context of conditions, duration, fluid intake and your own sweat losses, then test the decision in training.
The gel provides carbohydrate. The electrolyte sachet supports hydration without adding fuel. CoreCtrl is an eight-day pre-event preparation product. They solve different problems and should not be treated as interchangeable.
Practise timing, texture, flavour, fluid and total hourly carbohydrate during long training. Build gradually and include every gel, bottle and food source in the calculation.
Choose by job
Choose the Energy Gel for carbohydrate, Electrolytes for a separate mineral dose, and CoreCtrl only for a tested hot-weather preparation protocol.
