In top rope climbing or
lead climbing, there is a way to determine the safeness of a
climb by analyzing the distance that the climber will face
if they were to fall. This is called the fall factor. This
mathematical formula is represented by:
distance
fallen / available rope to absorb fall = fall factor
The fall factor is
used when determining the amount of force exerted on the
gear being used. The safeness of the fall the climber
could face increases as the fall factor decreases and
vice-versa.
The image below illustrates how as
the climber ascends, the factor of the fall they could
potentially face increases.
