How flattest 15k 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 15k route map questions
What qualifies for flattest 15k route maps?
A 15k race must have stored route geometry and a publishable flat grade share value to appear in this ranking.
Why are some mapped 15k 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 15k race leads this mapped-route ranking?
Lundaloppet leads this route-map ranking with flat grade share 71.2%.
