What this site is
Longevity Marathon documents one person's four-month marathon training and the observed effects on his own health markers. It is an editorial and educational project, not a research study, coaching service, or medical practice.
Medical disclaimer
Nothing on this site is medical advice, a diagnosis, or a personalized recommendation. Dr. Varun Reddy's involvement as a collaborator, and any commentary published under his name, does not create a clinician–patient relationship with readers and should not be treated as care directed at any individual reader. Health markers, plans, and outcomes described here belong to one person under his own specific circumstances; they are not transferable advice. Always consult an appropriately qualified professional for your own training, health, or medical decisions.
One person's experience
Findings on this site describe what happened to one individual and are not presented as proof of a general health effect. Where established research is cited — in Dr. Reddy's commentary or in the Explainers — it is linked and attributed separately from this project's own personal observations.
Content & corrections
Published content may be updated with a visible "Updated" date and note when a meaningful addition or correction is made. Original publication dates are preserved. Errors, when found, are corrected visibly rather than silently.
External links
Links to outside research, tools, or sources are provided for reference. This project doesn't control and isn't responsible for external site content.
Changes to these terms
