What this service is
Ultra Fuel Planner is a free online tool that helps trail and ultra runners plan fuelling strategies for their races and long runs. It generates estimates based on the inputs you provide — including past race data, GPX route files, fuel products and aid station locations.
It is an informational planning tool only. It is not a personalised coaching service, a nutrition programme or a medical product.
No professional advice
Nothing in Ultra Fuel Planner constitutes medical, nutritional, dietary, coaching or other professional advice. The plans and recommendations produced are general estimates based on widely used training principles and the data you enter.
You should use your own judgement when reviewing any output. If you have specific health conditions, dietary requirements or concerns about race nutrition, consult a qualified professional before acting on any guidance from this tool.
Use at your own risk
Fuelling plans produced by this tool are estimates. They are based on your inputs, assumed pace models and route data. Actual race conditions, your tolerance on the day, weather, fatigue and many other factors will influence what works for you.
You are responsible for testing any fuelling strategy in training before relying on it in a race. You are responsible for the decisions you make on race day.
No guarantees
Ultra Fuel Planner is provided as-is. We make no guarantees about the accuracy, completeness or reliability of any plan it produces. We do not guarantee that the tool is fit for any particular purpose, that it will be available without interruption, or that it is free from errors.
Limitation of liability
To the fullest extent permitted by law, the providers of Ultra Fuel Planner are not liable for any injury, illness, loss, damage or other outcome arising from your use of this tool or any plan it generates. This includes outcomes during training or racing.
Changes and availability
Ultra Fuel Planner may be updated, changed, suspended or discontinued at any time without notice. The terms on this page may also be updated. Continued use of the tool after any changes constitutes acceptance of the updated terms.
