The inaugural Russian Formula One Grand Prix in Sochi, the venue for next year's Winter Olympics, is expected to be staged on October 19, 2014, organisers announced on Wednesday.
Oleg Zabara, deputy chief of the Russian GP's organising committee, told reporters: "I'm happy to announce that the international Formula One promoter has set a preliminary date for the Russian Grand Prix on its calendar of season 2014.
"There are 450 days remaining before the first official Friday practice of the Formula One stage in Sochi's Olympic Park."
He added: "The construction works at the circuit are nearing completion and preparations for the first Russian Grand Prix are currently in full swing.
"We are looking forward to attracting more Russian and foreign tourists into the region by extending the holiday season in southern Russia.
"I am sure that Sochi will become an up to date and comfortable home for motorsport in Russia with its own inimitable style for all of the Formula One fans."
The new Russian leg of the F1 calendar received backing last Sunday from Jenson Button.
The McLaren driver driver, appearing at a Moscow City race day, said: "As a driver I'm really excited and looking forward to race at the new Grand Prix and in a new country as well.
"It's great for the fans to hear, to smell and to feel the F1 cars' speed."
