ABOUT THE 2026 iRACING PORTIMAO 1000
Endurance returns to Portugal with the iRacing Portimão 1000km, featuring a classic multiclass showdown at the Algarve International Circuit. HPD ARX-01c prototypes battle for outright victory while iconic GT1 and GT2 machines fight for class honors across nearly six hours of high-stakes racing. Precision, strategy, and survival will define this tribute to old-school endurance grit.
The Portimao 1000 was run for the first time in 2009 in International Sports Car competition. This weekend, from August 14th to the 15th, iRacing revisits these classic sports cars for 215 laps around Algarve International Circuit, in Portugal, a 1000 kilometer showdown in the iRacing multiclass, team racing format. As with most of our Team events, a minimum of two and a maximum of 16 drivers per team is in effect with fair share enabled.
This race is an open setup event and will be scheduled in the sim for August 15th at 10:00 AM. Dynamic weather is enabled as well.
This event is open to iRacing members that have a Sports Car license at Class C or higher, or at Class D with a 4.0 Safety Rating. Splits can have up to 60 teams, and a disqualification limit has been set at 100 incident points, or 100X per team. Stop and Go penalties will be administered after 35 incidents, or 35X, and every 20 incidents (20X) afterward until the limit is reached and disqualification occurs.

ABOUT ALGARVE INTERNATIONAL CIRCUIT
Commonly known as Portimão for the city in which it’s based, Algarve International Circuit is one of Portugal’s premier racing facilities. Breaking ground in early 2008 and opening later that year, it has boasted a full calendar of global and national events ever since. Twice the home of the Portuguese Grand Prix, the track has also hosted the 6 Hours of Portimão, numerous TCR events, and various other motorcycle, open wheel, and sports car races in that time.
A lap of Portimão is marked by heavy elevation changes throughout its 4.653 km (2.891 mile) layout. These big slopes mix with a varied selection of both tight and sweeping turns to produce one of the most old-school feeling laps out of any circuit to be built in the 2000s. You’ll have the chance to sample all of its variations through both its Grand Prix and Moto configurations, each of which are available both with and without chicanes.
