2019 TWC respects IAAF trail rules. With semiautonomous character, the race goes through the Louzan Mountain range which reveals the cultural and human side of the Schist Villages in a unique manner, with the nature and the leisure options that this landscape provides. It is home to deer, wild boar and bucks that lurk among cork oaks, chestnut trees, oak and, of course, pine trees. The athletes have the opportunity to pass through a biological park (with species originating from this mountain range), an environmentally protected area (Mestrinhas park), a sanctuary (Senhora da Piedade) and a shale village (Gondramaz).
