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 mix. Ensure to drink water as required.
1-2 hours
During this period, aim for 30-60 (45 average) 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.
