Wilhelminaberg Trappen Marathon 2026

The Wilhelminaberg Trappen Marathon course for runners includes a 248-meter staircase with 508 steps. This race takes place in Landgraaf, South Limburg, situated on the 93-meter Wilhelminaberg, which is the highest slag heap in the Netherlands. It is a lap-based road and stair race, offering distances from 5 km up to a marathon, alongside a kids run and a Business Run for teams of up to five. Each standard lap is 1,090 meters. Consequently, the 5 km requires 5 laps, the 10 km is 10 laps, the 10 mile is 16 laps, the half marathon is 21 laps, and the marathon is 42 laps. The full marathon involves runners ascending the staircase 44 times, totaling 22,350 steps. This is why Dutch media refers to it as the toughest marathon in the Netherlands. The kids run features a scaled-down version of the central element: it begins at the base of the stairs and concludes at the summit.
