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.

Mixed ultramarathons questions

What mixed ultramarathons are included?

This guide includes 59 ultramarathon race pages with source-backed terrain evidence for mixed.

Do all mixed ultramarathons have route maps?

No. 34 currently have stored route geometry and 19 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.
