F1 returns to Spain with Lewis Hamilton holding a narrow eighth point championship lead over Max Verstappen.
The Spanish Grand Prix was among the small number of races that retained its position on last year's calendar as F1 battled to continue racing through the Covid-19 pandemic.
The 2020 race took place behind closed doors but this year the Circuit de Barcelona-Catalunya will welcome 1,000 "circuit members" into the grandstands on race day, the day the "alarm state" ends in Spain.
After a disappointing pre-season test, Mercedes and Lewis Hamilton have recovered to take two wins from the opening three races. Max Verstappen and Red Bull were victorious at Imola and, despite Hamilton's dominance last time out at Portimão, the coming weekend will likely be another closely contested battle.
The circuit at Barcelona is extremely familiar to the teams and the drivers, with pre-season more often than not taking place at the circuit ahead of the annual race.
However, changes made to turn 10, the hard braking zone being removed to create a more flowing corner, will take some getting used to. How this will affect the racing, the braking zone previously being one of few overtaking opportunities on the layout, will become evident on Sunday.
