Route Master Statement and Route Diagrams

Since the 2025 Saimaa Challenge is located in the city and the competition center is reasonably close to the city center, this year's routes are characterized by more built environments and scenery than in previous years. Despite the proximity to the city center, the routes have been designed to ensure that as much of the movement as possible takes place on surfaces other than asphalt, and to disturb as little as possible.

Event information and rules

The Saimaa Challenge is a multisport adventure event.

In the event, two-person teams navigate from one checkpoint to another by running, (mountain) biking, and paddling in the order specified in the route book. The maps are distributed to the participants two hours before the mass start, after which the participants plan their own routes. The checkpoints feature the familiar orange-and-white checkered flag used in orienteering. Some checkpoints include tasks (quests) where participants must follow separate instructions. In longer series, these quest tasks test participants’ knowledge and skills in the sport; in shorter series, they provide memorable experiences.

The event’s Explore The series (lasting about 3 to 6 hours) is designed for those new to the sport as an accessible option that can be completed with a regular bike and basic navigation skills.

The Adventure The series (5–10 hours) offers a slightly greater challenge, but can be completed successfully even without prior experience in adventure races. The course has been made even easier for 2024.

The Challenge series (7–12 hours) is still slightly higher in terms of difficulty. In the Challenge series, the planning will be more challenging and the terrain will be more diverse.

The Extreme The series (15 to 22 hours) challenges participants both mentally and physically due to its length and physical demands. In terms of athletic skills, the demands are significantly higher than in other series. There are very few individual challenges.

The event takes time for all participants, and the best from all series are rewarded. In the Explore and Adventure series, winners receive a commemorative prize, but the actual prizes are drawn among the finishers. In the Extreme and Challenge series, prizes are awarded based on results to the top performers.
