How flattest relay 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 relay route map questions
What qualifies for flattest relay route maps?
A relay race must have stored route geometry and a publishable flat grade share value to appear in this ranking.
Why are some mapped relay 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 relay race leads this mapped-route ranking?
Daytona 100 Ultramarathon (Jacksonville Beach to Ponce Inlet) leads this route-map ranking with flat grade share 100.0%.
