"If you want to estimate the real distance that you will trek between two points, a good rule of thumb is to multiply by a factor of three the straight distance expressed in a map between your point of origin and your destination.

This marked increase is due to the twists and turns of trails and paths thorough rough terrain. It is impossible to make such estimations based on maps alone."
