I made a video (10 minutes) during the 100 kilometer race at Cycle Vision. Cycle Vision was in Sloten (near Amsterdam) and the races were held inside the velodrome and on the outside track. The 100 km. race ended when the fastest rider had done 100 km. Hans Wessels won in his orange Quest (100 km in 1:54:16 gives an average speed of 52,5 km/h ).
You can find the competitionresults here . I made the video in the first corner after the small bridge.
