How flattest marathon route maps qualify

A race appears in a route-map collection only when raceindex.org has stored route geometry. Elevation, ascent and GAP values appear only when the route has enough elevation-bearing evidence for a publishable profile; unsupported signals are omitted.

Flattest marathon route map questions

What qualifies for flattest marathon route maps?

A marathon race must have stored route geometry and a publishable flat grade share value to appear in this ranking.

Why are some mapped marathon races missing from this ranking?

Mapped races can be missing an elevation-derived metric when their stored route lacks enough elevation-bearing evidence. Unsupported route metrics are omitted rather than inferred.

Which marathon race leads this mapped-route ranking?

Naturosa Catania Marathon leads this route-map ranking with flat grade share 100.0%.
