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.

Island ultramarathons questions

What island ultramarathons are included?

This guide includes 20 ultramarathon race pages with source-backed scenery evidence for island.

Do all island ultramarathons have route maps?

No. 13 currently have stored route geometry and 11 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.
