Which Races Could a Rwanda Grand Prix Put at Risk?

If Formula 1 heads to Rwanda at the start of the next decade—assuming the circuit near Kigali is built—it will spell bad news for at least one of the current hosts on the World Championship calendar.

Formula 1 is set to sign further long-term hosting agreements, with Liberty Media having already clearly shown its preference for 10-year deals.

Which races, however, face an uncertain future in Formula 1 beyond the end of the current decade?

First in line are Mexico City, Portugal, and Singapore, whose contracts expire at the end of 2028. Portugal returns next year on a two-year deal, while Mexican promoters are also fighting for a longer-term extension.

The year 2029 marks the final season under Japan's current deal, while Abu Dhabi, Azerbaijan, China, São Paulo, and Saudi Arabia hold secured spots on the Formula 1 calendar through 2013.

Belgium—which is set to alternate with Barcelona—as well as Italy and Turkey have contracts running through the end of 2031. Barcelona's final race under its current deal is scheduled for 2032, with the same expiration date applying to Hungary and Qatar.

Looking further ahead, Great Britain and Austin are secured until the end of 2034, while Australia, Canada, Monaco, and Spain have deals through the end of 2035, followed by Bahrain through 2036. Las Vegas holds a guaranteed spot until 2037, with Austria and Miami locked in through 2041.

Of course, contracts are not always seen through to the end, and Madrid could prove to be the prime casualty. If changes are not made to the track layout to deliver more exciting racing, fan interest may dwindle—and with it, the "Madring's" place on the calendar.
