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.
Race history After the Dutch government relaxed laws allowing the motorsport racing on public roads, the Assen & Omstreken motorcycle club organized and held the first Dutch TT on July 11, 1925. Since then the event has taken place every year with the exception of the years 1940 to 1945, because of the Second World War, and 2020, due to the COVID-19 pandemic.
The 1925 races were held on a street circuit in the shape of a triangle between the towns of Borger, Schoonloo and Grolloo. From 1926 to 1955, the races were held on a rectangular shaped street circuit through the towns of De Haar, Hooghalen, Laaghalen and Laaghalerveen. In 1955, a new circuit was created which still used public roads but, more closely resembled a modern race track. In 1992, the race track became a permanent enclosed circuit.
The races were traditionally held on the last Saturday of June however, from 2016 onwards it has been held on Sunday of the last weekend of June, bringing it in line with all other MotoGP races.
