Cycling Nutrition / Endurance Fueling / Hydration
A beginner-friendly guide to carbs, hydration, electrolytes, pre-ride meals, during-ride fuel, and recovery. 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
- Carbs fuel the work.
- Hydration and electrolytes support the plan.
- Start simple, practice often, and avoid race-day experiments.
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.

Key takeaway
Carbs fuel the work. Build the plan around the full session, then keep the execution simple enough to follow when the ride gets hard.
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.
