How steepest 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.

Steepest relay route map questions

What qualifies for steepest relay route maps?
