Hi,

The best race-day fuel plan is a simple one. Carbs in your gel, electrolytes in your bottle, and a plan for the conditions you’ll face.

truefuels is now available in the US, exclusively at The Feed, and it’s built around exactly that.

It was co-founded by Alistair Brownlee, a two-time Olympic triathlon champion who spent his entire career looking for trustworthy race-day nutrition. In his words: “I wanted the system to be simple. If you need fuel, use gels. If sweat loss is high, add electrolytes. If heat is a major factor, prepare properly. The point is not to keep adding products. It’s to know what problem you’re solving.”

That’s the whole philosophy. Three products, one job each.

Beat the heat with CoreCTRL

Heat isn’t something you can fuel for last-minute. It’s something you have to prepare for in advance. When it’s hot, your body sends blood to your skin to cool you down, which pulls it away from your working muscles. Your heart rate creeps up, the effort feels harder faster, and the pace you trained for becomes difficult to maintain.

CoreCTRL helps your body defeat the heat. It pairs 4,000mg of L-taurine with potassium, calcium, magnesium, and Himalayan rock salt, plus a little black pepper extract to help you absorb the taurine. A 2024 study linked eight days of taurine to earlier sweat onset, a higher sweat rate, and less heat stored in the body during exercise. In other words, your body starts cooling itself sooner. The electrolytes replace what heat-driven sweat strips away, so your muscles keep firing and cramps show up later (or not at all).

Here’s how to use it: One sachet a day for seven days before a hot race, with the eighth and final sachet taken the morning of the big day. Mix each one sachet into 500ml of cold water. Reminder: CoreCTRL is not a race-morning fix. It requires you to get started with it a week before your race. It also works for heat camps and warm-weather training blocks.

Energy Gels

40g of carbs per gel, with electrolytes added right in. The twist is the salt: Low Salt (0.25g) for normal sweat, High Salt (1g) for extreme heat days or if you’re a heavy sweater. Same carbs either way, plus potassium and magnesium in every gel. Take one 15 minutes before the start, then increase or maintain based on the level of intensity and your sweat rate.

Electrolytes

400mg of sodium, 150mg of potassium, and 25mg of magnesium per sachet, built on a coconut water base with no added sugar. Available in mint or watermelon. Use it during training to replace what’s actually being lost, or right after to rehydrate.
