The Mariëndaaltocht takes place in Diest, a historic town in Flemish Brabant, and offers a spread of routes from 7 km up to a 50 km Hagelandse Heuvel Trail. Participants walk or run through the Hageland countryside around Diest, on a mix of forest tracks, country lanes and quiet local roads, with the longer options climbing into the low wooded hills that give the region its name. The shorter distances suit families and first-timers, while the marathon and 50 km routes are aimed at walkers and trail runners who want a full day on their feet. The event is held on a single Saturday, with the organizer's own calendar page carrying the latest details on start times and entry.
