What are 'double-headers' and 'triple-headers' in F1?
Traditionally, Formula One races were planned with a weekend-on, weekend-off approach, but an expanding calendar led to the introduction of double-headers and, in some cases, triple-headers. A double-header is a sequence of back-to-back Grands Prix on successive weekends, while a triple-header is three race weekends in a row. This allows for more races within the 52-week year.
