Following a 10-year absence, the FIM International Six Days Enduro (ISDE) will return to Portugal in 2019 for the first time since 2009.

Situated in the south of the country, the beautiful Algarve city of Portimao and its world-renowned Autódromo Internacional do Algarve will host to the 94th running of ISDE.

With its large, purpose-built facility, the international motor racing circuit will act as the paddock and centre hub of activity for the race. Utilising the surrounding mountainsides, three unique routes will be laid out incorporating a wide range of terrain for riders to contest.

The opening two days will be predominantly sandy, while days three, four and five offer a contrasting character of forest and rocky terrain that will take riders into the country’s highest mountain range.

Daily routes are expected to be around 300 kilometres each in length, ensuring both riders and machines will be tested to their absolute limits, while also enjoying breath taking scenery. With the official date yet to be confirmed, the 2019 ISDE is expected to be held between late October and early November.
