Raceday made a bar that helps delay fatigue during intense workouts

Endurance athletes use sodium bicarbonate to help delay fatigue during hard efforts, but the traditional formats — capsules or chalky drinks — are notoriously tough on digestion. Raceday’s new Bicarb Bar addresses that by pairing 21g of sodium bicarbonate with natural carbs in a bar you can actually stomach.

What’s in the bar

Raceday built its formula around whole food ingredients: dates, honey, oats, peanut butter, and dark chocolate, paired with sodium bicarbonate. Each full bar delivers 21g of bicarbonate alongside 52g of carbohydrates, 10g of protein, and 380 calories. The bar can be split in half for a 10.5g bicarbonate dose.

The carbohydrate blend is designed to serve double duty, fueling performance while also helping the bicarbonate sit more easily in your stomach compared to taking it on its own.

So instead of juggling a loading protocol with dozens of capsules and precise timing windows, the bar consolidates your bicarbonate and carb fueling into one step.

Why bicarbonate?

During high-intensity exercise, your muscles produce acid that contributes to that burning sensation and eventually leads to fatigue. Sodium bicarbonate helps neutralize that acid, which can delay when you hit that wall and help you sustain power output longer.

Traditional methods like capsules or dissolved powders require loading protocols and are notorious for causing GI distress. That’s kept many athletes from using it consistently, even when the performance benefits are clear. The bar comes as two halves, giving athletes flexibility on dosing—take both together for full buffering before effort, or split them before and after to support both performance and recovery.

Where to buy
