Monaco won the Principality Grand Prix for the fifth time in 2015
Formula 1 is dropping the Monaco Grand Prix to three days from 2022, according to the chief executive of the sport’s commercial rights holder.
Sean Bratches said that “in terms of durability and overall race, six days is not a best practice”.
As well as cutting the race from its traditional Saturday and Sunday, an executive told the BBC: “There may be more after that.
“This is about gaining a bit more efficiency.”
Monaco’s 2019 date will be on Friday 19 July and Saturday 20 July.
The decision to trim the race to three days is part of a greater F1 push to adapt the calendar to better reflect the sport’s more modern workload and deliver another British Grand Prix in 2020, Bratches said.
Part of the reason for the cuts, which take the race dates back from the Sunday of June to the Tuesday of June 13, was to ensure race weekends did not start late in the year.
Bristol, Long Beach and Grand Prix of America will be the other race on Fridays in 2021.
Monaco, held on a harbourside on the Mediterranean coast in the Principality of Monaco, has a long-standing Grand Prix tradition.
It is the fifth race of the season, while Long Beach, on the US coast in California, and Sydney’s 17-year-old Circuit of the Americas are the new entrants in 2021.
It will be the third weekend in a row with Friday and Saturday preceded by a practice session, something that could also be the case in Paris for the next Formula 1 World Endurance Championship race in 2020.
“The travelling [to test and race locations] will become easier and a lot of the race commission stuff will be easier, too,” Bratches said.
“We don’t want teams having to spend days at events travelling to faraway places, cross country.”
The executive said the schedule was “a starting point” for teams to look at in terms of possible format changes but added that “it’s very hard to implement change in F1 if there’s an embedded ego in the organisation”.
Asked if it could lead to a change in the format of the race, the executive said: “Some of the stakeholders will enjoy Friday and Saturday more, but yes, we are heading down that direction.”
