Bulbjerg to Agger (50 miles), 5
Hanstholm to Agger (50 km), 5
Nr. Vorupør to Agger (24 km) 5

along the old lifeboat road and the West Coast Trail on the northwest coast of Denmark.

The event is a low-key trail running race without too much fuss. Our priority is taking you onto the best trails in the area and giving you the most spectacular views.

Note that the first half of the 100 miles course is unmarked. Participants will have to navigate this part of the course using a GPS unit or a GPS running watch. The remaining half is marked using small orange flags. GPS navigation is not required to participate on the 50 miles, 50 km, 24 km, or 12 km courses.

More detail on the courses can be found on the dedicated Course page.

There are no mandatory equipment requirements on the 12 km course.

We strongly advice all participants to check the weather forecast and dress accordingly. The course is remote in places and vehicle access can be limited. You may have to wait a while for help to reach you, should the need arise.

It is strictly necessary to bring a headlamp on the 50 miles and 100 miles courses. The sun rises around 07:00 and sets at 19:30. Plan your race and equipment accordingly.

On the 100 miles course it is strictly necessary to bring and use a GPS unit for navigation on the first unmarked half of the course. Both dedicated GPS units or GPS watches are permitted. A unit without a background map is sufficient, but we recommend bringing a backup unit with a background map, e.g., a cellphone.
As a backup unit we recommend the app Topo GPS which is available for both Android and iOS. The app allows you to import a GPX file and offers offline topographic maps of Denmark for DKK 29.
GPX files are found on the Course page.
