F1 2019 Russian Grand Prix: As it happened!

Click here for Crash.net's full live text commentary of the 2019 Formula 1 Russian Grand Prix from Sochi. 

For the fourth consecutive race, Charles Leclerc starts from pole position as he goes in search of Ferrari's fourth straight victory since the summer break at the Russian Grand Prix. 

Formula 1 heads to Russia for round 15 of the 2019 season, the Russian Grand Prix, which takes place at the 5.848km Sochi Autodrom. 

Ferrari heads into the weekend off the back of three consecutive victories at Spa, Monza and Singapore and is looking to make it four wins in a row for the first time since the 2008 season, following its surprise one-two finish in Singapore. 

Mercedes will be looking to bounce back and return to winning ways after a frustrating result in Singapore. The reigning world champion squad has not won a race since before Formula 1's summer break at the Hungarian Grand Prix. 

Russia has proved a happy hunting ground for Mercedes since its introduction to the calendar in 2014, with the German manufacturer dominating the event, winning all five races since the start of the V6 hybrid era in 2014. 

Mercedes is set to face its toughest test yet if it is to keep its 100 percent unbeaten record in tact at Sochi, with the emerging threat of the revitalised Ferrari team, which has hit a purple patch of form. 

The 2019 F1 Russian Grand Prix begins at 1410 local time, with lights out in the United Kingdom taking place at 1210 (BST).
