The Maasduinen Ultra is a 50 km trail running event that winds through the forests, sand drifts, and heathlands of the Maasduinen river dune belt in the Netherlands.

What this race demands

The Maasduinen Ultra demands steady pacing and resilient legs to cover 50 km of undulating terrain across winter sand drifts and forest trails.

Ultra Distance Endurance

Covering 50 km requires a robust aerobic base and the muscular endurance to sustain forward motion for hours on foot.

Terrain Adaptability

Navigating sand drifts and heathlands places continuous biomechanical stress on stabilizing muscles and requires efficient running mechanics on soft ground.

Winter Conditions

A late February date in the Netherlands means athletes must prepare for cold, damp weather and manage thermoregulation effectively over a long duration.

Aim for 60 to 90 grams of carbohydrates per hour to maintain energy levels over the extended duration of a 50 km ultra.
