My running partner and I are selling our spots for the Trail TO organized by O'bivwak, between 20 and 25 km per day (~2100m elevation gain over the weekend). It is located in Oyonnax for this 2026 edition and takes place over two days with a friendly bivouac. Your gear is carried by the organization due to the nature of the trail course. Following a fracture of my talus, I am unable to run it. You can contact me for more information. A name change is possible for an additional 10 euros per person via the organization.
