Overview
Starting in Hoek van Holland in January 2027, the Pierewaai Winter Trail 100k (nightrun) pairs a mostly flat course with demanding underfoot conditions. With 580 meters of elevation gain across the 100-kilometer point-to-point route from Hoek van Holland to IJmuiden—averaging just 5.8 meters of climb per kilometer—vertical gain is negligible, but the race covers 50 kilometers of flat beach and 45 kilometers of dunes, putting 95 percent of the race on sand.
That soft terrain collides directly with a 14-hour time limit. The required pace of 8.4 minutes per kilometer creates a cut-off tighter than 81 percent of 100k races and more generous than only 19 percent, leaving little breathing room on sand in the dark.
For an entry fee of €65, runners take on an intimate event where fields remain tiny. The 2026 edition saw just 10 finishers, reflecting a field smaller than 81 percent of 100k peers and bigger than 17 percent.
