It has a rolling terrain and most of the unpaved roads are used by four-wheeled vehicles. The composition of the unpaved road is a mixture of mud and gravel. Some portions have spillways for water streams which are passable to runners. This part of the route will cover the “big & outer” loop of the course. It has an estimated distance of 51 Kilometers.
The Fernandez Hill-Taklang Damulag Mountain Complex is where the route, which is called the “smaller & inner” loop, is located. One loop of this course has an estimated distance of 13.1 Kilometers. Most of the trails are single track with mud and slippery rocks. These trails cut across cogon grasses with sharp leaves and plants/vines with thorns on the sides of the trail. Water stream crossings and trees with exposed roots are plenty in this area. There are also portions where foliage is thick where runners would be disoriented on their direction, most especially during night time.
