“The Namosi trail is ineffably beautiful and exceptionally challenging. Each step through the lush Namosi forest, along its winding river, and over the rugged hills brings you closer to discovering the strength within you and the stunning beauty around. Running in Namosi offers a unique chance to conquer one of the world’s toughest trails, reminding you that you are capable of more than you ever imagined.”
