OK, my final pic on this thread.
This is my friend Matt (centre, in blue) approaching the spectator arera in the last stages of his race. He competed in the final race of the day, the Men's Elite category. He was unplaced, but finished in the top 6 or 7; not sure of the team result. The race was 1 hour, plus 3 laps.
The criterium is quite a tactical race - there is a lot of team tactics, breakaways etc, during the race, with a sprint over the 3 laps at the end.
This shot was taken with the 50mm f1.4 at 1/125sec, f11 (click for larger pic):
