Disclaimer

MilePaceLab results are estimates for planning runs. They are not medical advice, and they do not replace advice from a qualified health professional.

Health and exercise

Running can be hard on the body. Talk to a doctor before you start or change an exercise program, especially if you have a health condition, are pregnant, are returning from injury or have been inactive. Stop and seek help if you feel pain, dizziness or unusual shortness of breath.

Accuracy

We check calculations with automated tests and explain our methodology. Real races vary with weather, course, terrain, fitness and pacing, so a finish time from a calculator is a projection, not a promise.

No professional relationship

Using the site does not create a coach, trainer or medical relationship. Reviewers named on a page check accuracy of the content, not your personal fitness.

Advertising and links

The site may show advertising and may link to other sites. Ads do not change calculator results. If we add affiliate links, we label them. We are not responsible for third-party sites.

Your responsibility

You are responsible for how you use the results. See the terms of use and contact us if something looks wrong.
