Double Olympic triathlon champion Alistair Brownlee isn't just a legend on the race course—he’s now forging a path in sport nutrition with the launch of his TrueFuels line. With a message to athletes everywhere—“Don’t be scared of salt!”—Brownlee is shifting the conversation around electrolyte intake and fueling strategies for triathletes, marathon runners, cyclists, and all endurance enthusiasts.
From Olympic Gold to Fuel Innovation
Alistair Brownlee’s career is synonymous with grit, consistency, and world-class results. With gold medals from London 2012 and Rio 2016, his commitment to scientific training, recovery, and smart nutrition is legendary. After grappling with injuries and changes in the professional triathlon landscape, Brownlee recognized a need: practical nutrition tools rooted in pro-level experience, not just marketing. That mission became TrueFuels, his new line of energy gels and electrolyte products designed for real-world racing and training.
The Crucial Role of Electrolytes—Especially Sodium
When endurance athletes sweat, they lose both water and essential minerals, especially sodium. Prolonged loss without replacement can impair muscle function, delay nerve signaling, and, in extreme cases, lead to dangerous conditions such as hyponatremia. Brownlee’s core message—backed by years of elite racing—challenges athletes to rethink their mindset about salt:
- Sodium supports optimal hydration: It aids the body's ability to absorb and retain water, reducing the risks of cramping and heat-related performance drops.
- Electrolyte balance matters as much as carbs: Replacing carbohydrates is only half the battle; sodium, potassium, magnesium, and calcium are indispensable for energy conversion and muscular endurance.
- Individual needs vary: Brownlee’s mantra is to test your sweat rate and tailor intake—not only in hot or long races but during tough training sessions and multi-day events.
For triathletes and trail runners, who often face hours on the move, failing to replace sodium can mean the difference between a strong finish and a DNF (Did Not Finish) due to cramps, GI distress, or even confusion.
Inside the TrueFuels Line: What Makes These Gels & Electrolytes Special?
Brownlee’s nutritional philosophy is uncompromising: clean ingredients, science-driven formulations, and real-world usability. The new TrueFuels range features:
- Energy gels with balanced electrolytes, including higher sodium than many competitors to reflect real sweat loss—not just the bare minimum.
- Electrolyte mixes designed for easy absorption, with deliberate salt content and low artificial additives.
- Practical flavors and digestion-friendly formulas, borne from Brownlee’s own experience battling GI issues in hot, humid races.
Brownlee notes that many amateur athletes still hesitate to intentionally add sodium, fearing old myths about salt and health. But in endurance sport, the right amount of sodium is performance insurance. As he says, "Don’t be scared of salt—be scared of not having enough when it counts!"
Fueling the Endurance Engine: How to Use Gels and Electrolytes Effectively
No two athletes are the same, but Brownlee’s advice starts with these evidence-backed principles:
- Practice in training: Use energy gels and electrolytes in your long sessions well before race day. This helps your gut adapt and reveals your unique needs.
- Monitor sweat losses: Weigh yourself before and after a session to estimate fluid loss. If possible, use sweat testing to tailor your sodium intake more precisely.
- Pair carbs and sodium: Combine gels (for carbohydrate) with electrolyte drinks or capsules (for sodium) for sessions over 90 minutes or in heat/humidity.
- Individualize your plan: Some athletes, especially salty sweaters, may need 600–1000mg sodium per hour. Listen to your body, track your performance, and review post-session feelings.

Expert Perspective: Why Salt Still Matters
Despite growing awareness, many recreational marathoners and age-group triathletes still underfuel and underhydrate, particularly on sodium. Scientific consensus is shifting—in recent years, expert position statements (notably by the American College of Sports Medicine) underline that sodium needs rise with intense and prolonged exercise.
Practical example:
During the 2012 Olympics, competitors in humid conditions averaged sodium losses significantly higher than standard sports drinks provided. Brownlee’s own experience aligns with research: replacing sodium losses during multi-hour events helps delay fatigue and prevents debilitating cramps.
Conclusion: Rethinking Salt for Performance
Alistair Brownlee’s TrueFuels initiative is more than a product launch—it’s a practical call to update old nutritional assumptions. Endurance athletes invest countless hours in training, but race-day success often comes down to smart, individualized fueling. Integrating sodium and balanced electrolytes into your strategy is no longer optional.
Whether you’re prepping for your first sprint triathlon, a marathon, or an Ironman, don’t fear salt—understand it, test your needs, and make it part of your performance toolkit. Like Brownlee, you may discover that the right approach to electrolytes is the missing link to your best endurance self.
🧠FAQ - Energy gels, electrolytes, and salt for endurance athletes
âť“ Are energy gels with added salt necessary for most endurance athletes?
For sessions over 90 minutes or in hot/humid conditions, energy gels with adequate sodium can help prevent cramps and support sustained performance. For short efforts, salt may be less critical.
âť“ How do I determine my personal sodium needs?
You can estimate sweat rate by weighing yourself before and after training sessions and observing signs like heavy salt residue on clothes or skin. Professional sweat testing offers precision but is not required for most athletes.
âť“ Can too much salt be dangerous during exercise?
Excessive sodium intake without matching fluid can cause discomfort and, rarely, medical issues. Most athletes, however, are more at risk from too little sodium than too much during long, sweaty efforts.
âť“ What is the best way to use energy gels and electrolytes on race day?
Practice with specific products during long training to train your digestive system. Alternate gels with water and use electrolyte drinks or capsules as needed based on sweat rate and race pace.
âť“ Aren't sports drinks enough for sodium replacement?
Many commercial sports drinks are low in sodium compared to actual athlete losses. Combining higher-sodium electrolyte products or gels may better match your individual needs.
âť“ Should recreational athletes care as much about sodium as elites?
Yes—the fundamental physiology applies to all. Individual sweat rates, conditions, and event durations matter more than performance level. Anyone training or racing over 90 minutes should assess their electrolyte strategy.
