BRUT

BRUT is a science-based fuelling and training companion for endurance athletes. We make electrolyte capsules and build the digital tools that tell you when and how to take them.

What we make

BRUT capsules deliver 211 mg of sodium each — calibrated for the losses real endurance athletes face, not generic sports-drink assumptions.

Around the capsules we build deterministic planning tools: single-session fuelling (BRUT TRAIN), full periodised race programmes (BRUT RACE) and complete race-day strategies (BRUT RACE DAY).

How we plan

Methodology over magic. Polarised 80/20 training (Seiler), carb periodisation through phases, hydration grounded in physiological baselines (Baker 2017, Barnes 2019, ACSM). Every recommendation comes from a pure function with the assumptions visible.

What we are not

We are not a coach. We are not medical advice. Our plans are a structured starting point you adapt with experience, sensation and professional guidance.
