Not medical advice

The calculators, charts and articles on GrowLytics Run are provided for general information and training guidance only. They are not medical advice and are not a substitute for advice from a doctor, physiotherapist, registered dietitian or qualified coach.

Estimates, not guarantees

Race predictions, training paces, heart rate zones, calorie figures and similar outputs are estimates based on published population-level models. Individual results vary, sometimes substantially. Always adjust training by how you feel and stop if you experience pain, dizziness, chest discomfort, unusual breathlessness or any other worrying symptom.

Consult a professional first

Speak to a doctor before starting a new exercise programme, increasing training significantly or performing maximal efforts such as max heart rate tests — particularly if you have a medical condition, are pregnant, are returning from injury or illness, or have been inactive.
