Each gel and drink is part of one system. 45 g Triple-Carb in a 2:1:1.5 maltodextrin, glucose, fructose ratio with 343 mg sodium. Built for high-volume fuelling by engaging multiple absorption pathways, keeping osmolarity in range, and maintaining sodium levels. The result is sustained energy, tolerance at higher intakes, and hydration support as pace and duration increase.

How to use & the ecosystem
The use of 02 During depends on your training duration and intensity:
Less than 1 hour
The body typically has sufficient glycogen stores for activities under an hour, so additional carbohydrate intake isn't necessary. However, for high-intensity sessions (Zone 4/5), consider using 02 During: Drink. Ensure to drink water as required.
1-2 hours
During this period, aim for 45 grams of carbohydrates per hour, equivalent to 1 unit per hour. Remember to monitor hydration and replace electrolytes as needed.
2+ hours
For extended endurance activities, consume two units or 90 grams of carbohydrates per hour.
