The race will end with eight laps on the 'Champs whatever' if it is dry. If wet it ends on the first crossing of the finish line. If dry but it starts to rain it ends on the next crossing of the line.
Champs whatever - I like that. I don't know how to pronounce it, and I sure as heck can't spell it... Champs whatever would probably upset the French too, so it's a winner all around.
