Overview
- Organisers issued 47,000 start permits for the 108th Nijmeegse Vierdaagse, with the most entrants signed up for the 40 km (18,665) and more than 10,000 registered for the 50 km.
- The marches begin Tuesday and the first walkers depart at 04:00, with participants collecting wristbands and start papers in the days before the event.
- Event weather teams and national forecasters expect generally mild walking conditions of about 20–24°C while warning of isolated showers midweek, and final safety advice will be issued shortly before each day.
- The operation spans eleven municipalities, three provinces and four safety regions and must absorb hundreds of thousands of festival visitors during the concurrent Vierdaagsefeesten, putting heavy demands on logistics, volunteers and emergency services.
- Radboudumc’s 20 years of field research informs on-site medical planning with findings on dehydration, body-temperature rise and cardiac markers, while organisers note growing youth participation and the long‑standing gender‑linked distance rules that shape who walks which route.
