MotoGP World Championship · TT Circuit Assen, Netherlands
The Dutch Tourist Trophy, also known as the TT Assen, and also sometimes known as the Dutch Motorcycle Grand Prix, is an annual Dutch motorsport event established in 1925 for road racing motorcycles held on the TT Circuit Assen, also known as the ‘Cathedral of Speed'. The event attained world championship status in 1949 when it was sanctioned by the FIM as part of the inaugural Grand Prix motorcycle racing world championship season, making it the oldest event on the MotoGP calendar. The venue holds the record for being the only circuit to have hosted a motorcycle Grand Prix event every year since the series was created in 1949, with the exception of 2020 when the race was cancelled due to the outbreak of COVID-19. The event is due to take place at the TT Circuit Assen until at least 2031.
