How it works

From event details to race-card instructions.

Endufueler keeps the workflow close to how athletes actually prepare: define the course, pick the fuel, generate the card, pack the kit.

1
Set the event

Distance, duration, heat, intensity, body weight, and bottle capacity define the race constraints.

2
Choose products

Use real drink mixes, gels, sodium capsules, or custom fuel instead of generic servings.

3
Generate the race card

Endufueler turns targets into timed fueling instructions for race-day execution.

4
Pack what matters

Leave with exact quantities, prepared fluid volume, sodium support, and assumptions called out.

Features

Built for race-morning decisions.

The planner stays operational: timing, constraints, product math, and warnings are visible without turning the page into a lifestyle dashboard.

Course-aware timing

Fuel events stay practical, and warnings remain visible when timing or product volume gets risky.

Real product math

Plans are built from product serving data so the output reads like the things you will actually carry.

Fluid and sodium lanes

Carbs, fluid, and sodium stay separated enough to scan quickly before the start or during packing.

Race-morning packing

The planner converts targets into gels, bottles, packets, and practical rounding.

Planner ready

Use the planner when the plan needs numbers.

The landing page explains the workflow. The planner turns your event, fuel products, bottles, and aid stations into a working card.

FAQ

Know what the plan is, and what it is not.

Endufueler keeps calculations practical and visible, but race nutrition still needs training validation.
