Sprint Calculator is a free web-based tool that uses machine learning models (including XGBoost) to predict sprint performance times across distances ranging from 10m to 200m. The Service also includes supplementary tools such as the Race Conditions Converter, informational pages, and affiliate product recommendations.
The Service is provided for informational and training-support purposes only. Predictions generated by the calculator are statistical estimates based on historical race data and should not be interpreted as guaranteed performance outcomes.
You agree to use the Service only for lawful purposes and in a manner consistent with its intended use. You must not:
The predictions provided by Sprint Calculator are generated by statistical models trained on real competition data. While we strive for accuracy, all predictions carry an inherent margin of error (Mean Absolute Error, or MAE), which is displayed alongside each result.
We do not warrant that any prediction will match actual competition performance. Factors such as individual athlete condition, race conditions, equipment, and environmental variables not captured by the model may all affect real-world results.
Sprint Calculator predictions should be used as a training and planning reference only. We accept no liability for decisions made — including training, competition, or betting decisions — based on the outputs of this Service.
The Gear page of Sprint Calculator contains affiliate links to products on Amazon. As an Amazon Associate, we earn a small commission on qualifying purchases made through these links, at no additional cost to you.
