Overview

The Pierewaai Winter Trail 70km (nightrun) is a point-to-point winter night race starting in Hoek van Holland, Netherlands, scheduled for January 22, 2027. With only 150 meters of total ascent across the 70-kilometer route—averaging 2.1 meters of climb per kilometer—the profile is exceptionally flat, though 95 percent of the running surface consists of sand across 50 kilometers of beach and 20 kilometers of dunes.

A 12-hour time limit demands a minimum pace of 10.3 minutes per kilometer. That cut-off is tighter than 69% of 50-mile peer races and more generous than 31%, leaving limited room for prolonged walking through the heavy sand sections in the dark.

The event drew 35 finishers in its 2026 debut, making its starting field bigger than 38% of 50-mile races and smaller than 62%. Entry is set at €57,50 for the fixed-course trail race.
