What qualifies for flattest marathon route maps?
A marathon race must have stored route geometry and a publishable flat grade share value to appear in this ranking.
Why are some mapped marathon 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.
