It is purely down to costs, at the moment Longchamp is being upgraded.
There are so many racecourses in France, if I was to put up a list here it would drop off the screen.
When I sat down and compile a set of french standard times, due to the number of racecourses, we settled on only the class 1,2 and 3 racecourses, the provincial class 4 racecourses I didn’t bother with.
Can you imagine compiling standard times for 200+ French racecourses, you would get an entry in the Guiness book of records…
Mike.
