Week in activities: 19 February

In Flanders, walking is something of an obsession. This week there are public walking events in three locations: Opwijk (Flemish Brabant), Dienze (East Flanders) and Ypres (West Flanders). In Ypres, the trail winds through the front lines of the First World War, with routes between 5km and 35km.
