About Running Toolkit
Running Toolkit is a collection of simple, transparent calculators for runners who want practical planning numbers without black-box outputs.
Who Maintains This Site
Running Toolkit is maintained by Hiddenwork Development. The site focuses on clear formulas, source links, and plain-language limitations so runners can understand how each result is produced.
Editorial Review Policy
Calculator formulas and methodology notes are reviewed when source standards change, when new calculator types are added, or when implementation tests reveal a mismatch between the published method and the calculation code.
Health and Training Disclaimer
The tools are for planning, education, and comparison. They are not medical advice, nutrition prescriptions, coaching plans, or lab measurements. Consult a qualified professional for personal health, injury, nutrition, or training decisions.
