General Use

RunCalc provides running calculators and training explanations for general informational and educational use. We aim to make the tools accurate and useful, but we do not guarantee completeness, fitness for a particular purpose, or error-free results for every use case.

You are responsible for checking whether a calculator's assumptions match your situation before relying on the output.

Health and Pregnancy Content

Training, fueling, hydration, recovery, heart-rate, and similar running calculators on RunCalc are not medical devices. They do not provide diagnosis, treatment, or personalized medical advice.

If you have symptoms, take medication, manage a chronic condition, or need to make a medical decision, use these tools only as a starting point and consult a qualified clinician.

Training, Gear, and Race Decisions

RunCalc can help you compare paces, estimate race outcomes, plan fueling, and think through gear timing, but it cannot know your full training history, injury risk, weather exposure, course profile, or race-day support.

Before making a high-stakes training or racing decision, validate the output against your recent training, official race information, product instructions, and qualified professional guidance where appropriate.
