Calendar FAQs

Does this page list every 24-hour race?

No. It lists the source-checked events currently included in the Multiday Running directory. Organizer and federation calendars may include additional races.

How are past 24-hour races handled?

A listed edition moves into the archive after its end date. Its page remains useful for research, but runners should check the organizer for a newer edition.

Where can I learn how a 24-hour race works?

Use the separate 24-hour race format guide for rules, pacing demands, training, nutrition, gear, and planning resources.
