Terms of Use

By using SwimRunPace you agree to these terms.

Calculations are estimates

Pace, finish time and calorie results are mathematical models, not measurements. Race performance depends on training, weather, course and health. Do not treat a predicted time as a guarantee or a target you must hit.

Training risk

Endurance training carries a risk of injury. Nothing here is medical advice. If you have a heart condition, are pregnant, or are returning from injury, consult a qualified professional before following any training pace or plan suggested by these tools.

No warranty

The tools are provided "as is" without warranty of any kind, express or implied, including fitness for a particular purpose.

Acceptable use

Use the calculators freely, including with athletes you coach, with attribution appreciated. Do not resell the site as a service, scrape it at volume, or present the formulas as your own original work.

Third-party names

Daniels, Riegel, Ironman, Garmin and other names are trademarks of their respective owners and are used descriptively. SwimRunPace is independent and not affiliated with any race organiser, equipment maker or coaching body.

Limitation of liability

To the maximum extent permitted by law, SwimRunPace is not liable for damages arising from use of the site, including missed race goals or injury.
