We met a group of Norwegians and Swedes on BSJ last year as they had a TV-set up and ready for Germany vs Poland.
Didn't ask for the distance, but they did it in 31hrs, only refuelling stops as they came with an old bus prepared for the race with sleeping area kitchen and so on.
For me it's the Le Mans 500

(miles)
I have to pit three times during the "race" for fuel
