Choosing a race from this collection

Check the published distance and course format together. A timed challenge with a marathon option and a fixed-distance race have different arrangements. Surface, distance certification, elevation and entry status are separate facts. Follow the organiser’s current information before deciding.

The main marathons page also keeps races awaiting a next date separate from confirmed editions. An earlier edition is useful context, not evidence of a future date or unchanged route.

Marathon race directory — page 7

Browse the announced upcoming marathons in date order. Each edition keeps its own date, surface and official event link; several editions can belong to the same race.

For date, surface and nearby filters, return to the main collection. Nearby results use the existing approximate-area rules; this list does not receive your location.

462 upcoming editions across 375 race families. Showing 241–280. Dates assessed for this list on 7 November 2026.

The list date is not a new source check. Each edition retains its recorded check date below; entry availability can change. Awaiting-date and past editions are not counted as upcoming.
