Since 1999, there is a Tour of Flanders Cyclosportive for non-professionals, called We Ride Flanders, organized on the day before the professional event. The longest route is 230 km (140 mi), starting in Antwerp, but there are three shorter routes, of 174 km (108 mi), 140 km (87 mi) or 74 km (46 mi), which all start and finish in Oudenaarde.[130] Because of its growing success, the number of participants has been restricted to 16,000 in order to secure riders' safety on the roads.
