Why this page is source-backed

Race-character guide pages publish only when enough race pages have a controlled-vocabulary character tag, verified facts and stored race-character source fact ids. The guide does not infer terrain, scenery, atmosphere or elevation character from a race name alone.

Trail 12ks questions

What trail 12ks are included?

This guide includes 14 12k race pages with source-backed terrain evidence for trail.

Do all trail 12ks have route maps?

No. 7 currently have stored route geometry and 6 have elevation profiles. Race pages without stored geometry show route-review status instead.

Why are some 12k races missing from this guide?

A race appears only when its race-character row is backed by verified source facts and the guide has enough qualifying race pages to avoid a thin page.
