GT42 - A technical maratrail for the belgian Championships 2023 !

Running a full marathon is already particularly difficult.

The Grand Trail des Lacs et Châteaux has been selected to organise the next Belgian Short and Long Trail Championships 2023.
The GT42, innovative with its UTMB index 50K, has been selected to represent the most contested race in the short trail version.

But what would you say about GT42, to which we added more than 1820 m D+ of vertical drop? GT42 is a technical maratrail across the Warche valley. This is sheer madness! A delight just like the other beautiful places crossed such as the lake of Robertville, the Vieux Chêne (the Old Oak), the Reinhardstein Castle, the Route des Crêtes, Napoleon’s nose, and more…

The alternation between technical parts, single tracks, rollings, climbs and downhills.

Only those who are members of a club recognised by the Belgian Athletics Federation will be able to compete for the various titles at stake and thus qualify for the world championships.
The race is open to all!
