Dated trail no. 2: “10,000 steps a day is a WHO recommendation”

A dated trail takes one sentence that institutions repeat and asks a single question: how old is it, and who wrote it first? Not “is it true”. When. The answer is a set of revision ids and timestamps you can check without trusting me.

The claim this time: 10,000 steps a day is a World Health Organization recommendation. Millions of people still organise their day around it, and their watches ship with it as the default goal.

1. The sentence, as it stands

English Wikipedia, article “Samsung Health”, current revision 1367800899 (2026-08-05 07:25:07 UTC), section Pedometer:

The default goal is to reach 10,000 steps per day. This number would be a recommendation of the World Health Organization according to the French Federation of Cardiology.

2. Its citation

The reference points to fedecardio.org/objectif-10-000-pas, titled “Objectif 10 000 pas”, with a Wayback URL pinned to 18 September 2016. The live page is gone: captures after 2016 return 301s and 404s.

The archived page opens with:

L'Organisation Mondiale de la Santé (OMS) recommande 10 000 pas par jour.

So Wikipedia is quoting its source accurately, and hedging while it does it (“would be ... according to”). The problem is one hop further back, which is where trails usually live.

3. When the sentence entered Wikipedia

The article has 135 revisions. Walked oldest first, the sentence is present in revision 1, 822326702, 2018-01-25 19:02:02 UTC, editor Patrik L., edit summary “New page”. No citation was attached at that point.

The citation arrived two days later: revision 822613309, 2018-01-27 12:46:41 UTC, same editor, summary “References”.

So this page cannot date the claim: the claim was in the first draft. What I can date exactly is the repetition. That is the difference between this trail and trail no. 1, where a revision existed before the sentence did and I could name the edition that came just before it.

4. The age of the cited page

Wayback's CDX index for that URL lists captures from 2013-12-31 00:17:21 UTC onward. The earliest capture already opens with the same OMS sentence. So the French cardiology federation was repeating the claim at least as early as 31 December 2013, and the page it lived on is now dead. Wikipedia's citation resolves to a sentence in an archive.

5. The last hop

WHO's own physical activity fact sheet, fetched 26 October 2026: the string “step” appears zero times anywhere in the page's markup, and the recommendation is given in time, at least 150 minutes of moderate activity a week, 300 for more benefit. The 2020 WHO guidelines say the same in the same units.

Where the number does appear in WHO material, it appears as an event target: a 2019 WHO Viet Nam speech for a walk-for-health challenge says 5,000 steps is about thirty minutes and that the challenge is “10,000 steps per day”. Campaign copy, not guidance.

The authority was borrowed from the organisation's name, not from a document.

6. Where the number actually comes from

1965, Japan: Yamasa Tokei Keiki sold the manpo-kei, “10,000 steps meter”, around the 1964 Tokyo Olympics, after a physician raised the alarm about inactivity. Reported in the Financial Times in 2016 (Leo Lewis, “A Japanese first-mover in the fitness wearables race”); the same account is standard in BBC Future (2019) and Harvard Health (2019, quoting I-Min Lee). I did not read a Japanese primary source. I am reporting that this account is well sourced, not that I verified it myself.

What I did not establish

That the French federation was the first to attribute the number to WHO. I dated their page, not the idea.
That no WHO document anywhere uses 10,000 steps. I checked the fact sheet, the guidelines, and one country-office speech. That is a sample, not a corpus.
That the sentence will stay. Anyone can edit the article tomorrow, and that is the point of giving the revision id instead of the sentence.

How to re-run this without me

# current wikitext curl “https://en.wikipedia.org/w/api.php?action=query&prop=revisions&titles=Samsung%20Health&rvprop=content|ids|timestamp&rvslots=main&format=json&formatversion=2"

# the whole revision list, oldest first curl “https://en.wikipedia.org/w/api.php?action=query&prop=revisions&titles=Samsung%20Health&rvlimit=max&rvdir=newer&rvprop=ids|timestamp|user|size|comment&format=json&formatversion=2"

# one revision, by id curl “https://en.wikipedia.org/w/api.php?action=query&prop=revisions&revids=822326702&rvprop=content|timestamp&rvslots=main&format=json&formatversion=2"

# every capture of the cited page curl “http://web.archive.org/cdx/search/cdx?url=fedecardio.org/objectif-10-000-pas&output=json"

# the WHO fact sheet curl “https://www.who.int/news-room/fact-sheets/detail/physical-activity"

The method, four steps, unchanged from trail no. 1: find the exact sentence in the current page; read its citation; walk the revisions to the edit that first added it; name the earliest revision with no trace, so the birth date is a bound and not a guess. Where there is no earlier revision, say that instead of inventing a bound.

Trail no. 1, for the index

Flower's Cove, Newfoundland: the thrombolites are “about 650 million years old”. That number entered Wikipedia in revision 509481427, 2012-08-27 19:36:49 UTC, by Torbenbrinker, cited to Hampstead's Atlantic Canada (Moon, 2012), page 380. Revision 437495382 of 1 July 2011 contains no thrombolite text at all. The number is repeated by the town, the tourism board and a Smithsonian page, and the earth-science caption that comes closest to a measurement puts the structures in the Cambrian, roughly 500 million years ago.

Two trails, same four steps, no improvisation. Two more and the method is either real or it isn't.
