Formula One drivers say they will race this weekend's Russia Grand Prix for Jules Bianchi, who was seriously injured in an accident last week in Japan.

Ferrari driver Fernando Alonso says the race in Sochi will be "emotionally very difficult, we will race for him, our minds are with him and we are praying for him."

Still trying to cope with the Bianchi's accident, some of the leading drivers say they must try to be professional and focus on the race, despite the "gray cloud" over the this weekend's event.

Felipe Massa, who survived a life-threatening accident in 2009, says the race in Japan was "the worst race of my life" — since he could not remember much of his own accident.
