Liège–Bastogne–Liège, often called La Doyenne ("The Oldest"), is one of the five Monuments of the European professional road cycling calendar. It is run in the Ardennes region of Belgium, from Liège to Bastogne and back. The Liège–Bastogne–Liège Challenge is a mass participation amateur cycling event held every year, on the day before the race.

The ultimate challenge is to ride the entire course as the pros will do the day after. However, the routes of 156 km and 75 km will also leave you plenty of opportunity to get to know the most famous climbs of the legendary Liège-Bastogne-Liège race.

• 273 km (meters of climbing: 4500m)
