Editorial Policy

Purpose

Our purpose is to help runners prepare for multiday ultras with practical, source-aware, safety-conscious guidance. We do not publish content only because a keyword is available; every page should help a runner make a better decision.

How We Research

• Official race and governing-body sources for rules, formats, records, and events.
• Peer-reviewed primary research, systematic reviews, and clinical consensus statements for health-adjacent claims, with direct links where possible.
• Manufacturer documentation for mutable product facts, clearly separated from independent testing or performance evidence.
• Practical race systems evaluated against fatigue, crew access, weather, and course format without presenting editorial judgment as experimental proof.

Health and Safety Content

Training, hydration, sodium, sleep, injury, and recovery content should state uncertainty, avoid diagnosing readers, avoid universal prescriptions, and include red flags when symptoms may require race medical staff or a clinician. A bibliography alone is not enough for a consequential claim: the relevant sentence should make clear which source supports it.

Unless a page names a qualified clinical reviewer, it has not been represented as clinician-reviewed. Source review is not a substitute for an individualized assessment from a physician, registered dietitian, physiotherapist, or other appropriately qualified professional.

Product and Affiliate Content

Gear pages are separated from educational pages and carry an affiliate disclosure where relevant. Current comparison guides are primarily desk-researched unless they describe a hands-on protocol. Their scores express editorial fit within a shortlist; they are not lab measurements or evidence that every product was personally tested. See the gear review methodology for more detail.

Updates and Corrections

Pages with changing facts, including records, event dates, product specs, and prices, should identify a meaningful verification or update date. We do not change a date without reviewing the affected claims and links. If you spot a factual error, email hello@multidayrunning.com with the page URL and source.

What We Avoid

• Fake certainty around medical, nutrition, or performance outcomes.
• Hidden sponsored influence.
• Changing dates just to make old content look fresh.
• Gear claims that imply hands-on testing when the evaluation was source- or spec-based.
• One-size-fits-all training prescriptions.
