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.

Road ultramarathons questions

What road ultramarathons are included?

This guide includes 62 ultramarathon race pages with source-backed terrain evidence for road.

Do all road ultramarathons have route maps?

No. 34 currently have stored route geometry and 21 have elevation profiles. Race pages without stored geometry show route-review status instead.

Why are some ultramarathon 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.
