We got our hands on THE Electro HYROX at the HYROX World Championships in Chicago, where Myprotein was a constant presence — from athlete bags to warm-up areas to recovery zones. It’s one of the centrepieces of the new HYROX-specific range, designed in direct partnership with the sport to meet the demands of functional fitness athletes.

Hydration might not be the first thing you think about when training for HYROX,  but it becomes one of the most limiting factors on race day. With average race times over an hour and a format that mixes cardio intensity with muscular fatigue, many athletes hit a performance wall due to poor fuelling and dehydration. That’s the problem THE Electro HYROX is built to solve.

The formula combines four essential electrolytes,  sodium, potassium, magnesium, and calcium,  with fast-absorbing carbohydrates. This helps athletes stay hydrated and maintain energy availability during prolonged or repeated effort. It’s not just for race day either: we saw athletes using it throughout the weekend in Chicago, during recovery workouts, long training sessions, and in the build-up to their events.

Importantly, the product is Informed-Sport certified, meaning it’s been batch-tested for banned substances — a key trust factor for competitive athletes. The flavour is mild and easy to drink, even during intense efforts, and it mixes cleanly with water without any gritty texture or excess sweetness.

Compared to standard electrolyte tabs or off-the-shelf sports drinks, THE Electro HYROX feels more purpose-built. It reflects the pace and structure of HYROX — where athletes move from machines to functional stations under cumulative fatigue, often in dry, indoor environments. Effective hydration here isn’t about comfort — it’s about performance preservation.

While no supplement replaces training, preparation, or pacing, this one offers real utility. Whether you’re aiming to finish strong, shave time off your splits, or simply recover better between workouts, THE Electro HYROX is a smart addition to the toolkit.
