text: International Six Days Enduro
Winners ISDT 1913–1980

The International Six Days Enduro (ISDE), formerly known as the International Six Days Trial (ISDT), is the oldest 'off-road' motorcycle event on the FIM Calendar. The ISDT was first held in 1913 at Carlisle, England. It has occurred annually, apart from interruptions due to World War I and World War II, at various locations throughout the world. The early events were a true test of machine, rider skill, and reliability. Held on the 'roads' of that era, today most of the routes are truly 'off-road'. Originally titled the International Six Day Trial, in 1981 the FIM decided to update the name to International Six Days Enduro, the name Enduro having been devised by the Americans and popularised by many motorcycle manufacturers also greater reflected the change in the event from a trial to more akin to a rally featuring skills more associated with cross country motocross. The sport has been associated with many great motorcyclists before its 100th anniversary in 2013; this also includes women such as 1920s-30s star Marjorie Cottle. Up until 1973 the contest was always held in Europe. In 1973 it travelled for its first overseas jaunt, the United States. Since then it has been outside Europe more frequently: twice in Australia (1992 and 1998), once more in the United States (1994), Brazil (2003), New Zealand in 2006, Chile in 2007 and 2018, and Mexico in 2010. The 2014 event was held from the 3 to 8 of November in San Juan, Argentina. The event has attracted national teams from as many as 32 different countries in recent years.
