It is necessary to adapt walking to the different types of terrain.
In order to prepare knees tendons and feet, it is important to adapt walking to the different types of terrain. Thus, on a flat surface, the length of the step will be normal; on going uphill, we can take shorter, slower steps in order to avoid excess exertion. In the stages with prolonged uphill stretches, it is very important to support the complete sole of the foot on the ground in order to prevent excess muscular load. Long rapid steps are reserved for going downhill, but the type of terrain must be taken into account before speeding up the steps. Going downhill, part of the work falls on the heels, therefore, it will be necessary “to stamp” them properly on the ground, without forcing them so as to prevent injuries.
