Hello, I think there is a translation error, because I don't think that a hillclimb has 73 "tours" (laps)?! Did you mean "virages" (turns)? (The error is also present for Lakeview) EDIT: Like @ChatCureuil said, it's the same for all tracks (but you can actually make laps around those ).
You're quite right, in both the English and German version of the portal it says "turns", which makes much more sense. I blame J-F and his deteriorating French skills. So what's your guys suggestion, "virages"?
