The Ohm, measurement unit of effort resistance perfectly symbolizes this trail which is full of difficulties, to cite just a fex examples: an elevation of 1950m D on the 35km race, which is a record in Belgium. You will also alternate technical passages, single tracks, crossings, mounts and descents. However, what makes the attractiveness of this event is his track. A beautiful course that takes the trailers through nature reserves, trails that are comparable to those found in the mountains in France and its path will make you discover the splendid wild region of Aywaille as the terribly beautiful valley of Ninglinspo, varied in every sense of the term, playful and spicy... A treat just like the other places passed through: the hedge Gattes, the Quarreux Fund and other enchanting places. True trail as hard as beautiful, the Ohm trail will make you suffer with a smile!
