Race Day / Fueling Plans / Cycling Nutrition
How to use aid stations without letting them derail your fueling plan. 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.
Start with the event demands
- Decide what you need before you arrive.
- Separate quick grabs from longer stops.
- Reset the plan after leaving instead of guessing.
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.
Make the plan boring before race day
Race-day fueling should feel familiar. Test breakfast, bottles, gels, chews, real food, sodium, caffeine, and backup options in training. If a product, serving size, or timing pattern has never been tested at a similar effort, race day is a risky time to discover whether it works.
Use this in a BonkGuard race plan
Start on Race Day with the event date, distance, and expected finish time. Review editable carbohydrate and fluid targets, reveal optional sodium guidance when it is useful, then choose the foods, gels, chews, drink mixes, and bottles you expect to carry.
Use Overview to compare targets with Planned intake from the generated schedule and prepared bottles. Check Schedule for timing, Packing for quantities and bottle preparation, and Practice this plan for a shorter rehearsal before you decide the plan is Race Ready.

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.
