The Hollands Duin Ultra is a challenging 50 km trail run taking participants through the dunes and along the beach of the Hollands Duin nature reserve with start and finish in Noordwijk.
What this race demands
The Hollands Duin Ultra demands sustained endurance and pacing discipline over a 50 km distance across coastal dunes and sandy beaches in winter conditions.
Distance endurance
Covering 50 km requires a deep aerobic base and the muscular durability to sustain forward motion over several hours of continuous trail running.
Terrain adaptability
Navigating dunes and beaches in the Hollands Duin nature reserve places high demands on stabilizing muscles and ankle strength due to soft, uneven footing.
Winter thermal regulation
A December event date in coastal Netherlands means athletes must manage exposure to cold, wind, and potential moisture over a long duration.
Given the duration of a 50 km trail run, athletes should target 60 to 90 grams of carbohydrates per hour to maintain energy output throughout the event.
