Inside this collection

Trail marathon choices across the UK

As of 7 Nov 2026, this collection contains 236 announced upcoming editions across 194 race families. These figures describe this directory before personal filters, not every event in the area. 57 families are awaiting a next date outside that total.

Surfaces in the announced editions

Road: 0 of 236
Trail: 236 of 236
Mixed: 0 of 236
Track: 0 of 236
Surface not confirmed: 0 of 236

Surface follows each edition. It does not measure hills, certification or difficulty.

How the distance is offered

Fixed distance: 78 of 236
Lapped: 40 of 236
Distance option in a timed challenge: 112 of 236
Format not recorded: 6 of 236

A timed challenge offers a distance option within its own rules. Read the published distance and format together; an unrecorded format is not assumed to be fixed distance.

Where these editions are listed

England: 217 editions / 175 families
Scotland: 0 editions / 0 families
Wales: 15 editions / 15 families
Northern Ireland: 4 editions / 4 families

Counts above use this surface selection; the linked nation pages include all surfaces.

Announced editions by month

Only months with upcoming editions are shown. Later dates depend on organiser announcements; these figures do not describe seasonal demand.

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.

Trail marathons

Find trail marathons with an announced upcoming date. Surface follows the specific edition: mixed, track and unconfirmed surfaces are not included in this collection.

Trail describes the recorded surface; it does not establish climbing, route marking or technical difficulty. Check the organiser’s current course information.

236 upcoming editions across 194 race families. Showing 1–40. 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.
