Terms of Service
Plain-English terms covering use of the PaceSplit running calculators.
Nature of service
PaceSplit is an informational site offering free running calculators. Every result is an estimate derived from published formulas — not professional coaching, training prescription, or medical advice. If you’re unsure whether a workout, race target, or heart-rate zone is appropriate for you, talk to a qualified coach or clinician.
Limitation of liability
The calculators are provided as is, without warranty of any kind. PaceSplit and its operators are not liable for training decisions, injuries, race outcomes, or any other consequences you draw from the results shown on this site. Use the numbers as one input alongside your own judgement, your training history, and — when the stakes are high — qualified human guidance.
Intellectual property
The site’s content, calculator implementations, copy, and visual design are the property of PaceSplit. The formulas themselves are drawn from published, peer-reviewed research and are cited on the Methodology page; attribution remains with the original authors.
Changes to these terms
We may update these terms occasionally as the site evolves. Continued use of PaceSplit after a change means you accept the revised terms. The “last updated” date in the footer reflects the most recent revision to the site overall.
