How much water should I drink with Unusual Fuel?

Santa Madre’s rule (one sachet in a 500 ml bottle): below 15 °C, one 500 ml bottle of plain water for every two bottles of Unusual Fuel; at 15–25 °C, one bottle of water per bottle of Fuel; above 25 °C, about 750 ml of water per bottle of Fuel. Carbohydrate absorption needs water.

Is Unusual Fuel for me?

It is built for very long events and for athletes who have trained high-carbohydrate strategies: 100 g of carbohydrate and 500 mg of sodium per 500 ml bottle. Santa Madre reports cyclists sustaining over 150 g per hour with it. If you are not there yet, CarboFuel 45CHO (45 g per bottle) is the gentler start.

CarboFuel 45CHO or Unusual Fuel 100CHO?

CarboFuel is the everyday drink: 45 g at a 1:0.5 ratio with 400 mg of sodium per 500 ml, for any effort over an hour, up to about 90 g/h. Unusual Fuel doubles the dose — 100 g at 1:1 with 500 mg of sodium — for very long events and gut-trained athletes.

Can I take 90–100 g of carbohydrate per hour straight away?

Santa Madre says no: high-carbohydrate strategies need an adaptation period — training the digestive system to work during exercise. Build up the amount per hour in training before trying it in a race.

Ratio 1:1

Equal glucose-type carbohydrate and fructose, equalising the workload of the SGLT1 and GLUT5 transporters. Santa Madre says it pioneered the 1:1 ratio in its line in 2022 and uses it in its UNUSUAL range for strategies of 90 g per hour or more — which, it stresses, need a trained gut.

Vegan, gluten-, lactose- and palm-oil-free

Santa Madre’s data sheets list this line as 100 % vegan and free of gluten, lactose and palm oil.
