ExtraTrail is a network of trails in the Ardennes in Eastern Wallonia, Belgium, specifically designed for trail and ultra run training. The routes are designed in circles from 7 villages (easy access by car or public transport) each having 4 routes of different length and elevation (green, blue, red and black). Due to the landscape all the trails have significant ascent/descent and very technical stretches, ideal for training. The loops are also interconnected to form a network with possibility to design longer circles or A to B routes. In fact, the 158 km UTDS is designed by combining all of the 7 villages using this network. All black courses of ExtraTrail are above 30 km and have more than 750 m accent, which makes them tough and slow.

GPS Track


When doing this route be carefull of the signs, I got off track twice and also did a return run at some point since I missed a sign. I did almost 44 km instead of the 40.
