The Russian Grand Prix proved to be perhaps the most exciting and unexpected race of the 2021 Formula 1 season. Lando Norris was on the verge of victory for much of the race, but the rain came with four laps to go. Hamilton changed his slick tires for intermediates and that was the moment that changed everything. In the end Norris did not change his tires and sold his defeat. Hamilton's 100th victory in Formula 1.
