Trail in the Kings’ North Zealand - Denmark

Trail & Ultra Running – From the renaissance cobblestones to the cool single tracks in dense forests across rolling commons and countryside, along lakes and beaches – you'll rarely see a more beautiful, tougher, and more cohesive trail in the National Park Kongernes Nordsjælland (Kings’ North Zealand).

Whitsunday – 2018 May 20th – marks the day of our Firkløver (Four clover) Ultra 50/50 Trail event at which you can choose one of the 4 challenging distances:

  • 50+ miles ultra trail run
  • 50+ km ultra trail run
  • 15+ miles trail run
  • 15+ km trail run

So why not visit the forest and have a fantastic trail run. Join us for the party in the start and finish area.

If you simply can’t get enough trail running and the challenge isn’t big enough on Whitsunday, you may also register for the Firkløver Ultra 15/50/50 "The Real Deal" which is 15 miles on 19th May; 50 miles on Whitsunday and then 50 km on Whitmonday – 100 miles ultra trail running over 3 days. This is a challenge, that only the fittest trail runners should take on.

The four leaves of the clover link the trails in Danstrup Hegn, Gurre lake, Teglstrup Hegn, and Egebæksvang via Krogenberg and Nyrup Hegn.


Registration is open!
