Start at Vaterlandsparken

From the start near Vaterlandsparken, the runners will experience Akerselva River for the next 10 kilometres. The river Akerselva is the "vein of the city", running from the lake Maridalsvannet, which is Oslo's main supply of drinking water, through the city's most populated areas, ending in the Oslo Fjord. The river has significant value for the people of the city in many ways. Akerselva has a rich history connected to the industrialisation, which started around the year 1850. However, at the same time, it is today living proof of Oslo people's need for recreation in green areas and beautiful nature. Akerselva is an important part of Oslo's cultural heritage – great for a walk or bicycle ride, you can go fishing or swimming, or explore the rich animal and plant life along the river.


The runners will then run along the drinking water Maridalsvannet and continuing out into Nordmarka. Crisscrossed by hiking trails and cross-country ski routes, the forested hills and lakes that comprise the Nordmarka occupy a tract of land that extends deep inland from central Oslo, but is still within the city limits for some 30km. A network of byroads, as well as two T-bane lines (#1 and #3), provides dozens of access points to this wilderness, which is extremely popular with the capital’s outdoor-minded citizens. Den Norske Turistforening (DNT), the Norwegian hiking organization, maintains a handful of staffed and unstaffed huts here and the runners will after 20 km reach Bjørnholt Tourist Hut at Hammeren – The entrance to Nordmarka. 


From Hammeren the trail continues along Songsvann one of the most popular recreational areas in oslo for running, Bathing and outdoor activities. Songsvann station is the end station and easy accessible with T-Bane line 6 for spectators.


 Frognerseteren means the seter ("mountain dairy farm", roughly comparable to shieling) of Frogner (Manor). Frognerseteren and parts of the Nordmarka forest (Frognerseterskogen) was part of Frogner Manor until 1848. Jacob Benjamin Wegner, the owner,  sold the rest of the estate but kept Frognerseteren. Wegner's heirs sold Frognerseteren to Thomas Johannessen Heftye in 1864, and Heftye's  sold Frognerseteren to Christiania municipality in 1889.

Frognerseteren will give the runners a glimpse into the history of Norwegian farming combined with a view of the City of Oslo and the Oslofjord itself.


Ecotrailers will reach Holmenkollen is a neighborhood in the Vestre Aker borough of Oslo. More than  a residential area, it has been a famous ski recreation place since the late 19th century, thanks to the eponymous, ski jumping hill, the Holmenkollbakken, hosting competitions since 1892. The ski jump was constructed from branches and covered in snow. The longest jump was recorded at 21.5 metres and the first hill record was set by Arne Ustvedt. The current record is 139 metres and was set by Andreas Kofler from Austria. Holmenkollen Day, which is held annually in March, gathers thousands of spectators in a cheering atmosphere.

The runners will fully exhale the excitement and the steep jump itself passing directly beneath the jump.
