The 2021 Formula 1 calendar is an ongoing puzzle for Formula 1 management. Because of the coronavirus, it remains uncertain which Grands Prix can and cannot take place, and that makes F1 not only need a plan B but actually also plan C to Z.
On to Qatar
F1 has done a good job with this because again a gap has been filled. The Australian GP that was already postponed to November as the first race of the year was later cancelled. This gap in November had not been filled until now but Qatar has been found as a suitable replacement. It will be the first F1 race ever held in Qatar.
The country that will host the FIFA World Cup in 2022 doesn't need to create a new circuit though. The Losail International Circuit already had a Grade 1 license and has been on the MotoGP calendar since 2004. However, it will now make its debut on the F1 calendar in 2021.
