Engineered in India · Launching 01.01.2027

Talent is a variable.
Protocol is a constant.

Fueling, hydration and recovery for people who compete on endurance, engineered by scientist-athletes, and tested where you actually race.

The research before the product. No spam, only splits worth reading.

The result is decided long before the start line.

You have done the sessions. You have the engine. Then somewhere in the last third, the stride shortens, the legs start negotiating, and the day slips away from you. That is rarely a fitness problem. It is almost always a fuelling one.

Indian athletes have had two options: import something formulated for another climate and another body, or improvise at home with no rigour behind the mix. Both are fair responses to a real gap. Neither is a system.

Pace holds while the tank does. Illustrative, not measured.

Your tank holds about ninety minutes.

Muscle glycogen runs to roughly 400–500 g when you are fully loaded. At threshold you spend it at 2.5–4 g every minute. Do that multiplication for a long race and the problem states itself: demand meets the whole tank, and then asks for more.

Everything we make starts from that curve, and from the second one: what your gut can actually absorb while you are working. We publish both before we sell anything.

Illustrative. Depletion varies with body mass, pace and starting load.

Three problems.
One system.

Fuel

Carbohydrate your gut will actually take while you are working, the constraint that decides the last third of a race, not the first.

C-Series

Hydrate

Built for the sweat rates an Indian afternoon actually produces, and for how differently each athlete loses salt. Your partner's plan is not your plan.

S-Series

Recover

The hours after the effort, where the adaptation you trained for is actually built, and the session most people skip.

U-Series

Start-line corrals are limited.

The founding cohort gets the protocols and the calculators before anything goes on sale. Not a newsletter. A bib number.
