Energy Gel 40/1.0g Salt
Tom C.

I finally found race-day fuel that works for me, as I sweat heavily and lose a lot of sodium. It's so easy to mix with some water in a bottle and carry on my bike. It helped me achieve a 21-minute PB in a Half-Ironman race this summer.

Simply great. I dissolve it in 500ml which I pre-cool over night in the fridge and it is the absolute best fuel I have ever tried!

Take the opportunity to try Truefuel gels , you won’t be disappointed. I have tried many brands over the years with
varying success but these are what I have been searching for. The addition of salt with 40 gram of carb will be my go to for training and race day . My marathon fuelling sorted . Excellent product backed with excellent customer service.

Tried these for the first time last week and i can honestly say that i did see an improvement in my performance. Noticeably during a 3 x 15 min race effort on the bike, a workout i never quite achieve, seen me hit my targets and goals with relative ease. looking at ordering more and looking forward to the water bottles becoming available on your website.

Having suffered with cramps in every heat wave and, after a bout of heatstroke, the sodium filled gels not only gave me 40g of quality carbs but kicked cramps to the past.
After 35 years of using gels this, without question, is the leader of the pack.

These new generation gels are a game changer. Loved them when I first tasted them at the Brownlee training camp. Now to put them into a race, when work allows me.

Needed to up my game with the Great North Run coming up so gave True Fuel gels ago. Worked fantastically well on my long runs and first try during a recent 10 mile road race on a pretty hot day.

Great product! Used the gels in training and racing and loved them. Easy to add to bottles water bottles to know your carb intake on the bike and easy to consume straight from the packet on the run without the need for additional water. No digestive issues either, definitely my energy product of choice!

I liked the high salt amount as I was running in a very sweaty environment. You could still improve a bit the sachet so that it doesn't leak anything but the effectiveness, taste and overall impression was absolutely great

Only what your body truly needs when sweating. Minimalist formulation focused solely on essential electrolytes; no sugar, artificial flavouring, or unnecessary additives. Great tasting. Stackable logic with truefuels gels provides precise carbohydrate and sodium control for every athlete and every condition.

One sachet mixes best with 500 mL of cold water. For a lighter taste, use up to 750 mL. Drink 30 minutes before exercise or 1-3 servings per hour during training.

Yes. The electrolyte is designed to complement the truefuels performance gels. This combination allows precise control of carbohydrates and sodium intake, based on heat and duration.

In high heat or heavy sweat conditions, increase intake to 1 serve per 20-30 minutes and prioritise higher-salt gels (40/1.0).

Sweat sodium losses range from 200 mg to over 2,000 mg per L. Adjust your gel and electrolyte combination to match your personal sweat rate for optimal performance and comfort.
