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.

Flat half marathons questions

What flat half marathons are included?

This guide includes 185 half marathon race pages with source-backed elevation evidence for flat.

Do all flat half marathons have route maps?

No. 75 currently have stored route geometry and 37 have elevation profiles. Race pages without stored geometry show route-review status instead.

Why are some half marathon 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.
