EAST35K is our original course which takes place for the fourth time in 2018. The race is divided into ten swims and nine runs and is characterized by technical off-trail running which has been highly appreciated by our contestants and equally, highly challenging to them. The longest run is 13,4 kilometres and the longest swim is approximately 750 meters.
The race starts with a swim from the beach at Breanäs to the western shore of the lake. From here competitors run north before reaching the shore and what is often, due to windy conditions, the toughest swim to Vejlön. After Vejlön the athletes reach the northernmost point of the race. From here the course leads south along the eastern shore of the lake, in another swim and the longest run of the race, before reaching Mjönäs. Straight after the longest run, the longest swim takes place which initiates a complete traverse of the lake. Having completed this stage that runs across 4 smaller islands, the contestants find themselves back on the western shore. The last part of the race is completed by running through beautiful beech woods, and a final swim across the southern most bay of the lake, to the finishing line at Immeln village.

Coming out of the water after the first swim a very scenic run on small trails is at hand. After one kilometer the run continues on gravel roads which is followed by offtrail running over a steep ridge. The distance between the ridge and the second swim is carried out on gravel roads.

There are no prepared trails on Vejlön so the crossing of the island is offtrailrunning through leaf and pine forests. The final part of the stage runs along the edge of a deforestation area.

The major part of this stage is carried out on gravel roads through beautiful forests. The final 500 meters are offtrailrunning through leaf and pine forests, leading up to a cliff, where the next swim starts.

This is the longest consecutive run of the race. It takes off on a path that after 500 meters changes to gravel road for another kilometer. Thereafter the athletes start to run along skåneleden through John Baueresque forests. Gravel roads of various character dominate the next part of this stage, that leads up to Ladbacken. The second half starts with a small stretch of tarmac which changes back to gravel roads leading through beautiful beech forests, before arriving at the next swim.

Once having terminated the longest run, the longest swim of the race starts which is followed by several shorter runs and swims that take the athletes across the central part of the lake. The athletes ability to frequently switch between swimming and running is thoroughly tested. The running is offtrail, occasionally simplified by paths carved out over the years by canoers and other visitors. The forests are sparse but the pace may be slowed down by blueberry bushes and heather.

The final stage of Immeln Swimrun East follows the western shore and is initialized by the toughest offtrail run of the race. The first two kilometers is a mixture of smaller gravel roads and steep offtrail tracks of which some lead across rocky ground where it is crucial to keep control on where to land your feet. After having passed a small lake called Ljumma sjö, which is connected to the main lake by a narrow canal, the terrain changes to smaller roads and paths that are nice to run on. The last part of the stage, that leads up to the last swim, goes through majestic and beautiful beech forests.
