Important links


During this Duathlon, the participant starts with his Mountain bike (MTB) at Lycée Belval (High School) to join the Fond-de-Gras, a historic cultural industrial site (21.2km). From the transition zone, the running circuit (9.6 km) leads you past the middle of a natural reserve called “Giele Botter” an ancient open pit mine. Once the highest point reached, the participant will have a panoramic view from an ancient rock face all over the mining area. Back at the transition area, the participant leaves with his mountain bike (MTB) to head to the finish at the High School “Lycée Belval” (18.2km). But be careful while crossing the small enchanted village of “Lasauvage” (The wild), not to run into the “wild” and thus follow a legend ….,

Participants are required to store their running gear for the Cross Duathlon in a bag they receive when collecting their race number. 

Bags must be handed to the organizers before the start (1 hour before start) of the Cross Duathlon in the area outlined on the site map (see participant’s guide).

All gear will be temporarily stored in the enclosed zone provided at Fond-de-Gras.
