How steepest 10k 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.
Steepest 10k route map questions
What qualifies for steepest 10k route maps?
A 10k race must have stored route geometry and a publishable max grade value to appear in this ranking.
Why are some mapped 10k 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 10k race leads this mapped-route ranking?
Dalmacija Ultra Trail leads this route-map ranking with max grade 48.6%.
