Like every area, even the sport field had to face problems and take action due to the Covid-19 pandemic.
Formula 1 was one of the first sports to be very efficient and to find solutions so that racing could continue.
Six of last year's 17 total races took place on new or old circuits.
The Mugello circuit in Italy and the Algarve International Circuit in Portimao, Portugal, had never been part of the Formula 1 calendar before.
The Nürburgring had not hosted F1 single-seaters for seven years, Istanbul for nine years and Imola for 14 years. The external circuit of Sakhir, which the commissioners decided to adapt as a new solution to the double weekend in the Bahraini desert, had never been covered before either.
These six races were not simple replacements for places that, due to the Covid pandemic and too long bureaucratic procedures, were unable to host F1. In fact, they have sparked an unexpected uproar in the media, showing that it is sometimes possible to get attention through very simple solutions.
In Emilia Romagna and Portugal, the slopes were the protagonists. Old school, spectacular curves, a varied layout, all enclosed in a great landscape, the Italian hills and the beautiful sea of Portugal. In Bahrain, the shortest circuit cars have covered, with lap times of 55 seconds, presented new tasks to aerodynamics and racing strategists.
Imola has enchanted everyone with its history and tradition, making up for the fact that on the Enzo and Dino Ferrari circuit there are not so many strategic points for overtaking.
The return to the Nürburgring aroused emotions in the hearts of all the fans, and despite the "lack" of approval from the public, Istanbul gave life to a fun GP, thanks to the combination of rain and new asphalt.
The success of these "new" circuits made the strategists of Formula 1 reflect.
"This was a lesson for us. We are thinking about how to incorporate this new and unknown factor in the future" admitted Formula 1 sporting director Ross Brawn to Auto Motor und Sport.
The 2021 calendar has been confirmed, with the first GP on March 28 in Bahrain, but it is good to be ready and organized to adapt to change, because, as already shown, Covid can change everyone's plans.
The Australian GP has already been postponed to November. The Chinese GP is, for the moment, out of the question. Imola and Portimao will feature in 2021 again.
Referring to the new Covid restrictions, it is very likely that there will be problems for the Singapore GP and the Japanese GP. It is currently difficult or impossible to enter both countries.
Maybe some city circuit could enter in the calendar as a replacement, but it's no simple matter.
"With new tracks, a lot depends on how much it costs to make them usable and safe for Formula 1. It might not be worth it on a permanent track. A street circuit is something different" Brawn said.
