Liege-Bastogne-Liege

Liège–Bastogne–Liège, also known as La Doyenne (“The Old Lady”), is a one-day classic cycling race in Belgium. First run in 1892, it is the oldest of the five Monuments of the European professional road cycling calendar; usually coming as the last of the spring classics. It is held annually in late April, in the Ardennes region of Belgium, from Liège to Bastogne and back. It is considered one of the most arduous one-day cycling events in the world because of its length and demanding course.
