Toto Wolff, Horner’s counterpart at Mercedes, has expressed concern that a 23-race schedule for the 2022 season will have a “toll” on mechanics, drivers and other employees.
F1 has long pushed to squeeze as many Grands Prix into the nine-month calendar as possible, but the pandemic has limited how teams can travel in the most recent two seasons.
Horner believes it is possible to run such a long campaign safely, as long as the teams and organizers do what they can to manage the paddock.
He told the Mail: “Everyone has choices in life. You could go to Formula 2 and do 12 races and make half the money.
“I think a lot of the guys in the paddock forget that 10 or 15 years ago we did testing in January and then the drivers and their race engineers would go from race to test to race to test.
“In terms of work balance, we don’t see a lot of mechanics in the factory between races because the cars aren’t there.
“I think it’s manageable if we go to the right places in the right order around the world.”
