Due to the coronavirus pandemic, the Qatar round was postponed to an unannounced date[1] and the Jerez,[2] Assen,[3] Aragon and Misano rounds were rescheduled to a later date, while the Imola[4] and Oschersleben[5] rounds were cancelled. As a result of updates made to the MotoGP calendar for the same reason, the French round date was also affected.[2] Despite having already been rescheduled, the Assen round was later postponed to a to-be-determined date, along with the Donington round.[6]
On 19 June, an updated calendar was published; for the restart, Jerez and Portimão were brought forward from their respective dates and a second round at Aragon was added to the schedule. Other five rounds—the first at Aragon, as well as Barcelona, Magny-Cours, San Juan and Misano—either kept their original or revised dates, although the latter two events were labelled as 'to be confirmed'. Three rounds—Losail, Donington and Assen—were included without a confirmed date[7][8] and were subsequently cancelled on 24 July.[9] The San Juan round was cancelled on the 13 August[10] whilst the Misano round was cancelled and replaced by a round in Estoril on 18 August.[11][12]
Along with the calendar, the event timetable was also revised, as an additional race to be held on Saturday was added to each remaining weekend.[13]
