Estimates, not measurements
Every figure produced by StepWheelTools is an estimate derived from a formula and the values entered. A formula describes an average of many people or vehicles; you, your bicycle and your car are specific cases. Differences of several percent are normal and expected, and each tool page states the known limits of its own method.
Health and fitness
BMI, body-fat percentage, heart-rate zones, calorie burn and energy requirements are provided for general education and planning only. They are not a diagnosis, not a treatment recommendation, and not a clearance to exercise. If you have a medical condition, are pregnant, are recovering from illness or injury, or are planning a significant change in diet or training load, consult a qualified clinician or coach first. Stop any activity that causes pain, dizziness or distress and seek medical advice.
Financial figures
Fuel and travel calculations cover fuel only and are not financial advice. Total motoring costs include maintenance, tyres, insurance, tolls and depreciation, which this site does not estimate.
Competitions and deadlines
Age, eligibility and pacing figures should be confirmed against the rules of the specific event or authority. Organisations apply their own cut-off dates and definitions, which may differ from general calculation.
