What classification of terrain allows for simple walking with gentle slopes?

The classification of terrain that allows for simple walking with gentle slopes is classified as Class 1. This class is characterized by terrain that is relatively flat or gently sloping, making it accessible and navigable for individuals without advanced technical skills or special equipment. In Class 1 terrain, walkers can maintain a steady pace with minimal physical exertion, which is ideal for hiking, casual walks, or training exercises.

Terrain classified as Class 2 usually includes slightly steeper slopes and may involve more obstacles, requiring some basic understanding of navigation or handling minor challenges. Class 3 terrain features steeper slopes and may necessitate the use of hands for balance or assistance, introducing more technical climbing aspects. Class 4 terrain typically involves even more severe slopes and complex features, often requiring specialized skills and equipment for safe traversal. Thus, Class 1 is distinctly the most suitable category for simple walking with gentle slopes.
