This video from www.bike-tube.com shows the build-up to the start of Paris-Roubaix at the velodrome where the race finishes.
It shows the work that’s involved from early morning, and the arrival of fans and team buses as the atmosphere builds. The stands and terraces gradually fill where the spectators can watch the action unfold on big screens, culminating in the arrival of the riders in the velodrome.
It will get you in the mood for Sunday’s race.
