The Monaco Grand Prix (French: Grand Prix de Monaco) is a Formula One Grand Prix held annually at the Circuit de Monaco in the latter half of May. It was first run in 1929 and is considered to be one of the most prestigious races on the motor racing calendar, being part of the Triple Crown of Motorsport. Run on the tight streets of Monaco, it is the slowest race on the calendar. Due to these slow speeds, it is run to 260 km (161 miles) rather than the typical 305 km (190 miles). The race weekend oddly sees Thursday practice sessions instead of Friday to accommodate for the Monaco nightlife.
