Official event pageWhat this race demands
Kustmarathon Zeeland demands sustained endurance over a full marathon distance combined with navigating diverse, unpredictable coastal terrain. Athletes must maintain pacing discipline through sand, dunes, and unpaved paths while managing high energy expenditure over several hours.
Distance endurance
Covering the full 42.2 km distance requires thorough aerobic preparation and structural resilience to sustain forward motion over an extended duration.
Terrain adaptability
The course features unpaved sections, forests, dikes, beaches, and dunes, requiring specific ankle and lower leg durability to handle soft and uneven surfaces.
A marathon-duration effort requires consistent carbohydrate intake of 60 to 90 grams per hour, started early in the race to sustain energy levels and prevent late-stage depletion.
