Trail marathon or road marathon?

A trail marathon is the same distance as a road marathon but rarely the same effort. Mud, climbing and rough ground mean finish times can be far slower than your road time, so race to effort rather than pace. Many events require kit such as a waterproof, and some need navigation.

The ultra pace calculator helps you plan around cut-offs, and if you want to go further, browse our 50K ultras.

How much slower is a trail marathon?
It varies with the course. Elevation and ground underfoot have the biggest effect, so look at last year's results to see how times compare with road.
Do I need trail shoes?
On muddy or rocky courses, yes. On hard-packed paths in dry weather a road shoe can be enough. Check the organiser's advice for each race.
