How flattest 5k 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 5k route map questions

What qualifies for flattest 5k route maps?

A 5k race must have stored route geometry and a publishable flat grade share value to appear in this ranking.

Why are some mapped 5k 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 5k race leads this mapped-route ranking?

Martian Invasion of Races leads this route-map ranking with flat grade share 100.0%.
