Cycling Nutrition / Fueling Plans / Bonking
How surges, drafting, stops, and social dynamics make group ride fueling harder. This guide is written for cyclists first, with notes that also apply to runners and triathletes when the same endurance-fueling principles carry over.
Good fueling is not about chasing a perfect number for its own sake. The goal is to deliver enough carbohydrate, fluid, and sodium for the session you are actually doing, using products and foods you can tolerate when the effort gets real.
A practical way to think about it
- Fuel before the pace gets chaotic.
- Use easy-to-open products when hand access is limited.
- Do not let the group decide your entire fueling schedule.
Set the carb target first
For many endurance rides, a useful starting range is roughly 30-60 grams of carbohydrate per hour for moderate sessions and 60-90 grams per hour for longer or harder events. Intakes above 90 grams per hour can work for some trained athletes, but they should be practiced gradually with multiple carbohydrate sources and products that sit well in your stomach.
The target should reflect ride duration, intensity, heat, your gut tolerance, and what you can realistically carry. A two-hour endurance ride and a five-hour event with climbs should not automatically use the same plan.
Use this as race-plan practice
Not every training ride needs race-level fueling. When a session is a deliberate rehearsal, open the race plan and choose Practice this plan to create a shorter linked plan with the full race target or a more conservative progression.
Use the rehearsal to review products, bottles, and timing, then adjust the race plan deliberately. Overview shows Planned intake from the schedule and bottles; Schedule and Packing show what the plan calls for. BonkGuard does not record consumed intake.

Educational note
This article is educational and is not medical or nutrition-treatment advice. Athletes vary widely in tolerance, sweat rate, health history, and goals. Practice fueling and hydration changes in training, not for the first time on race day, and work with a qualified professional when you need individualized medical or nutrition guidance.
