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.

Net Downhill half marathons questions

What net downhill half marathons are included?

This guide includes 32 half marathon race pages with source-backed elevation evidence for net downhill.

Do all net downhill half marathons have route maps?

No. 16 currently have stored route geometry and 6 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.
