Formula 1 2021 is speeding on to Barcelona this weekend as a hugely competitive season takes on its first double header - with Lewis Hamilton hoping to extend his narrow early title lead over Max Verstappen.
The Spanish GP is the fourth round of the season and Hamilton and Verstappen - the championship protagonists who have gone wheel-to-wheel in every race so far - are split by just eight points in the standings.

The whole weekend is live only on Sky Sports F1, with the race starting at 2pm on Sunday.
A return to Barcelona's Circuit de Catalunya, which is where F1 usually holds pre-season testing due to its balanced layout, offers another major challenge to the 10 teams, and should give a better indication of who out of Mercedes and Red Bull currently have the faster car.
The Formula 3 season also starts this weekend, with three races taking place over two days.
