Can't help thinking that calling Sochi remote because of the distance to Moscow rather misses the point about Russia.
Indeed.
The longest point to point distance in mainland France (let's ignore French Guyana!) is ~1065km, and Paris-Magny Cours is ~225km, so that's 21% of the distance.
The longest point to point distance in the main part of Russia (let's ignore Kaliningrad) is ~6000km, and Moscow-Sochi is ~1300km, so that's 22% of the distance.
It's basically the same.
