ATOBE ULTRA is our newest addition which spans from Hörvik, Blekinge, to our race arena in Immeln. The course starts off with roughly 30 km swimrun in marine environments to then link up with Skåneleden(famous hiking trail) for a roughly 50 km long trailrun, before plunging into Lake Immeln. From there the participants connect to the Immeln Swimrun course along the western side of the lake and ends with a lap on our SOUTH course. The preliminary total distance is 108 km, whereof 11 km swimming.

Stage 1: Hörvik – Sölvesborg. (Swimrun)

Distance: 27 km

Running: 23 km

Swimming: 4 km

Description: The race starts with a swim through Hällevik before taking a lap on the natural reserve of Listerlandet. The run follows trails with ocean views and ends with a tour of the southern headlands. A return swim across Hälleviks Bay follows(probably night) before a long run crossing multiple rural villages with lots of nature between them. During this run participants will most likely see a rising sun coming up from the ocean, welcoming them for two swims in Sölvesborg and with a final crossing of the scenic bridge before finishing stage 1. 

Stage 2: Sölvesborg – Näsum. (Trailrun)

Distance: 23,6 km

Description: This stage starts with a quick elevation gain up on Ryssberget. While travelling along small forest roads and rocky trails you’ll have big views in the east of Listerlandet. You’ll see hillsides of pebbles which indicate the Baltic icelake had its shoreline, some 12 000 years ago. 

On the ridge of Ryssberget you’ll run through the biggest beech forest in Blekinge. Here you will also make your first crossing of the border into Skåne. A few kilometers further along you’ll run through diverse forests and start to get a view over the valley of Näsum, which was an ocean bay 80 million years ago. This valley is famous for the discoveries of ancient dinosaur fossil, indicating that the area have gone through tremendous transformation. The stage ends with a descend into the valley, crossing small meadows before ascending on the other side. 

Stage 3: Näsum – Högön. (Swimrun)

Distance: 24,7 km

Running: 23,7 km

Swimming: 1 km

Description: Rounding the outskirts of the farmlands in the valley, just south of Östafors, you turn sharply westwards, towards the vast network of lakes connected to Immeln. Through diverse forest with some historic spots, you’ll have varying terrain. Some segments will go through wetlands where you’ll run on footbridges. Approaching Lake Raslången you finally get to plunge in the water again for an 800 m swim. While many hikers choose to make camp by the lake due to its beauty, we carry on towards the finish line. Another 9 km of wonderful trailrun awaits us before reaching Lake Immeln. With an almost movie like descent through Skärsnäs natural reserve you have joined the NORTH course. Make sure that you are prepared for some true swimrun. 

Stage 4 – Final Stage: Högön – Immeln. (Swimrun)

Distance: 33 km

Running: 27,5 km

Swimming: 5,5 km

Description: The final stage of the course offers some true swimrun in spectacular lake environment. Lake Immeln is our pearl and ATOBE ULTRA will connect to the traditional course in the northern part of the lake, via a descent through natural reserve Skärsnäs before swimming to Högön. Högön(The high island) offers some panorama views of the lake. From there participants will traverse the lake via headlands and islands that offer some technical trailrun as well as nice and soft, almost floating, running through a large spruce forest with moss covered floor. 

On the western side of the lake participants can enjoy some simple gravel road running until arrival in Breanäs. There follows a 450m swim, a traverse of a headland and another short swim. For the following run participants needs to muster up some energy for a step uphill on forest trails. This last for about 1km and thereafter follows 4km of smoother running before the swims in connection to Kvinnoöarna. Here you will be able to restock on energy.

The following section offers beautiful trailrunning through majestic beech forest. Be prepared for some small uphills once you reach the outskirts of civilisation, some of our previous races have been won in these parts due to strategic energy management. 

After a swim of 600m participants will cross the Race Arena and start a final lap on our SOUTH course. The eastern parts of that course offers varying running landscapes as well as picturesque bays for swimming. After reaching the edge of the headlands, a swim to Tjärön awaits and some island hopping before once again reaching the final western part of the course. The last swim this time around is different, and instead goes from the beach to the pier. From there participants will receive some well deserved cheers before finally crossing the finish line of ATOBE ULTRA.
