If you are already exploring enduro tours in Portugal, this one belongs at the very top of your list.

What is the Six Days Enduro? A Brief History of the ISDE

The FIM International Six Days of Enduro (ISDE) was first held in Britain’s Lake District in 1913, making it one of the oldest motorsport competitions in the world. Originally known simply as the “Six Days Trial”, the event was conceived as a test of both rider and machine endurance over six consecutive days of demanding off-road terrain.

Today, the ISDE is often described as the “Olympics of enduro”. It operates as a nations-based competition: riders earn points for their countries rather than competing purely as individuals. Teams from more than 30 nations across six continents take part, mixing world-class professionals with talented amateurs and club riders — a format that makes the event uniquely inclusive and electric in atmosphere.

The event has grown into a global celebration of off-road culture. Professional factory riders compete alongside amateur and hobby participants, all sharing the same trails, the same paddock frenzy, and the same mud.

Six Days Enduro 2026: Dates, Location and Format

Official Dates

The ISDE 2026 will be held from Monday 12 to Saturday 17 October 2026. The event will be based in Grândola, a town in the Alentejo Litoral region, approximately one hour south of Lisbon. The Paddock, Opening Ceremony, and Final Cross Test will take place in and around Grândola and the nearby Sines coastline.

Route and Format

The race follows a multi-day format in which riders complete timed special tests each day, linked by transfer stages. The daily routes cover between 250 and 300 km, with three special tests per day dispersed across the surrounding terrain.

Daily stages head west and north of Grândola for days one and two, then turn south towards Santiago do Cacem and the Atlantic coast at Sines for the middle stages. The final day’s Cross Test returns to Sines for the trophy ceremony — a historic setting for what will be a historic occasion.

Spectator Access

One of the most appealing aspects of the Six Days is its free entry policy for spectators. The Paddock, Opening Ceremony, Special Tests, Final Cross Test and parking areas are all free to access. This open atmosphere gives fans a chance to walk through the paddock, watch bike maintenance, talk to team members, and get up close to the action in a way that few motorsport events allow.

Why Portugal? The Alentejo as the Perfect Stage

Portugal is no stranger to hosting the ISDE. It has welcomed the event three times before: in Coimbra (1999), Figueira da Foz (2009), and Portimão (2019). Each edition confirmed Portugal’s place as one of the world’s great enduro destinations — and the Alentejo, having hosted numerous rounds of the FIM EnduroGP World Championship, is arguably its most versatile region for off-road competition.

The terrain offers everything: deep sandy tracks, rocky technical climbs, cork oak forests and open plains that stretch to the horizon. The FIM Race Director Pedro Mariano described the region as “well-supported for enduro, well-tested and well-received by riders — with a mixture of sandy and rocky terrain that will be a great challenge and enable some incredible special tests.”

Beyond the racing, the Alentejo Litoral is an extraordinarily beautiful part of Portugal. Rolling hills covered in cork and eucalyptus, whitewashed villages, medieval hilltop towns and a rugged Atlantic coastline combine to make this one of Europe’s most rewarding regions to explore on a motorcycle.

What to Expect at the ISDE 2026: Atmosphere and Highlights

The Six Days Enduro is unlike any other motorsport event. Its scale, its spread across the landscape and its open atmosphere make it something between a race, a festival and a pilgrimage for enduro enthusiasts worldwide. Here is what to expect:

The Paddock

The Grândola paddock will serve as the nerve centre of the entire event. Expect the arrival of hundreds of teams from across the globe, mechanics working around the clock, manufacturer displays, food trucks and a commercial village. The first riders begin to arrive into the paddock from approximately 3pm each afternoon, making the late afternoon the ideal time to soak up the atmosphere and watch the teams during maintenance windows.

Opening Ceremony

The opening ceremony will be held at Sines, on the Atlantic coast — a spectacular setting that will amplify the historic significance of the centenary edition.

Special Tests

Three timed special tests per day take place along the route. Most of the final special test of each day is located within 300 metres of the paddock entrance, making it easy to follow the racing and cheer on riders at the most important moment of each stage.

Final Cross Test and Trophy Ceremony

The final day concludes with the iconic Cross Test at Sines, where the World Trophy, Women’s Trophy and Junior Trophy winners will be crowned on Saturday 17 October 2026. For the 100th edition, this ceremony will carry extraordinary weight.

Riding to the ISDE: The Ultimate Way to Experience the Six Days Enduro

Watching the Six Days Enduro is unforgettable. Riding to it — on trails through Portugal’s hidden interior — is a completely different level of experience. Rather than simply arriving as a spectator, imagine exploring the very landscapes that the ISDE will race through, following gravel tracks and forest trails all the way to the paddock, and spending the afternoons watching the world’s best enduro riders in action. Portugal is one of the finest enduro destinations in Europe, and Andries Adventures runs a full range of enduro tours across the country — but none with the timing and the context of this one.

That is exactly what the 6 Days ISDE 2026 Portugal 100th edition tour offers: a carefully designed 4-day riding adventure that connects the Algarve to Grândola through some of the most rewarding trails in southern Portugal — timed to coincide perfectly with the event itself.

The 4-Day ISDE Experience Tour: Ride from the Algarve to the Paddock

The 6 Days ISDE 2026 Portugal 100th edition tour is built around the core idea that getting to the event should itself be an adventure. Starting in Tavira on the eastern Algarve, the route heads north through Portugal’s stunning interior over four days, before returning south to Tavira.

Day 1 — Tavira to Serpa

The first stage departs the Algarve beaches and climbs north through the Serra do Caldeirão mountain range — the natural border between the Algarve and Alentejo. On the other side of the range, the landscape opens into the sweeping plains of the Alentejo: cork forests, golden fields and the occasional white-walled village. The destination is Serpa, a town with Roman and Moorish roots and a castle ordered by Dom Dinis in the 12th century.

Day 2 — Serpa to Grandola via the ISDE Paddock

This is the day everything comes together. Heading west, the route rolls through open Alentejo terrain towards Grândola — the paddock city of the 6 Days Enduro 2026. Arrival is timed so that riders can explore the paddock as teams begin to arrive from the special tests. Night stop is at Lousal, a unique former mining village turned cultural heritage site.

Day 3 — Lousal to Castro da Cola via the ISDE Special Tests

Day three goes deeper into the heart of the Six Days, accompanying riders along the special test zones near Cercal and Sines. The morning involves riding alongside the race routes before peeling south after lunch towards Castro da Cola, one of Portugal’s oldest settlements, with origins in the Neolithic era.

Day 4 — Castro da Cola back to Tavira

The final day traces a scenic route southwest, crossing the mountain range once more and descending into the Algarve. Cork forests, honey beehives, medronho trees and eventually the Atlantic glittering in the distance signal the return to Tavira — and the end of a ride that will live long in the memory.

The tour runs for 4 days (with 5 nights in hotels), operates at a riding level adaptable for all riders (60% challenging terrain, 40% touring roads), and is priced at €2,580 per person. Nearest airport is Faro (FAO). Full details and booking at the 6 Days ISDE 2026 Portugal 100th edition product page.
