The 2025 Formula 1 season marks a significant milestone as the sport celebrates its
75th world championship since its inception in 1950.
This year’s calendar features
24 races, maintaining the expanded schedule seen in recent years, making it the third consecutive season with this number of rounds.
A notable shift in the geographic distribution of races is evident, with the number of European events declining from
11 out of 17 races in 2001 to just
nine in 2025, despite the overall calendar growth.
The composition of circuits has also evolved. While the calendar was once dominated by permanent racing facilities, there has been a rise in
street circuits and city venues such as Baku, Miami, and Las Vegas, reflecting Formula 1’s push towards urban settings and global expansion.
This transformation highlights the sport’s strategy to engage new audiences and markets, balancing tradition with innovation.
"The calendar was predominantly made up of permanent facilities 25 years ago, but since then the number of street circuits (Baku, Las Vegas) and dedicated city venues (Miami, Las Vegas) has risen," illustrating this trend.
As Formula 1 continues to evolve, the 75th season underscores both its rich history and its dynamic future, blending classic racing heritage with modern global appeal.
