Disclaimer

1. Health and training safety

Running and exercise involve physical demands and potential risks. Training suitability depends on your health, injury history, fitness, environment, recovery, and other circumstances. Increase workload gradually and use your judgment when selecting sessions.

If you have a medical concern, are returning after an injury, or are uncertain whether an exercise is suitable, seek individualized advice from an appropriately qualified professional. Stop exercising and seek appropriate medical attention if you experience concerning symptoms. Do not use our content to diagnose or treat a condition.

2. Calculators and estimates

Our running pace, race predictor, split, run/walk, cadence, and treadmill tools use mathematical formulas and user-provided values. Results may be rounded, rely on simplifying assumptions, or be affected by inaccurate inputs or measurement differences.

Predicted race finish times are estimates, not guarantees. Real performance varies with training, endurance, terrain, conditions, pacing, hydration, fueling, and other factors. Treadmill readings, estimated step lengths, and planned split schedules may differ from measured real-world results.

3. Running sessions and weekly plans

The Sessions library and Weekly Planner provide example structures to help organize training. They do not assess your medical history, current fitness, injury risk, or readiness for a particular workout. Plans should be adapted to your ability, recovery, available time, and relevant professional advice.

The presence of a workout in CalcStudio does not mean that it is appropriate for everyone. Recovery and rest are part of training; changing or skipping a session can be sensible when circumstances warrant.

4. Guides and tutorials

Blog articles and calculator tutorials are intended to explain training concepts, formulas, and practical examples. Examples are illustrative; they are not individualized prescriptions or promises of improvement. Information can become outdated as knowledge and recommendations develop.

We aim to present clear and useful information, but you should independently assess whether a recommendation fits your situation. You can read more about our content approach on the Editorial Policy page.

5. Accuracy and availability

We make reasonable efforts to keep the site useful and functioning, but we cannot promise that all information, outputs, features, or links will always be accurate, complete, current, or uninterrupted. Users should check important results independently before relying on them for consequential decisions.

6. External links and services

CalcStudio may link to third-party websites or services for additional information. We do not control their content, availability, or privacy practices. A link is not automatically an endorsement. If advertising is introduced in the future, the relevant policies and disclosures should be updated to reflect the services actually used.

7. Your decisions

You are responsible for deciding how to use the information and adjusting activities to your own circumstances. Nothing on this site should be interpreted as a promise of particular race times, health outcomes, or training results. This disclaimer does not limit any rights that cannot lawfully be limited under applicable law.

8. Questions or corrections
