Marathon — discipline page

evidence

The marathon distance is 42.195 km / 26 miles 385 yards, taken from the 1908 London Olympic course and set as the standard by the IAAF in 1921. V55 verification basis: worldathletics.org was refused by this session's network egress proxy, so the page was read only through attributed search summaries; the 1921 congress minute was not seen.

A evidence is not a place. Drawing it on a map would assert something about the world that no stored fact supports.
