BonkGuard
Cycling fueling planner for endurance sessions

Build a cycling fueling plan you can follow.

Fuel planning without the spreadsheet energy

The workflow stays focused: set the duration and target carbs per hour, choose the fuels for that plan, then follow a clear timeline.

Enter session length, target carbs per hour, intensity, start timing, and fueling interval.

Library

Store the fuels you actually use

Track carbs, calories, sodium, brand, name, and notes for default and custom fuels.

Reminders

Stay on schedule during the workout

Start a plan and use local notifications to reduce missed fueling once the session gets busy.

Reference

Export a timeline or stem card

Create a full fueling timeline PDF or a compact stem card for quick on-bike reference.
