For every kilometer 15 minutes for every contour climbed ADD 2 minutes
That way you will get a good guage on the time it will take plus add time for every box you find - 2 minutes per person.
Allow for break times as well
Hey Nik it's a good job you don't letterbox with us your estimation is very optimistic. When we walk normally we travel approx two and a quarter miles an hour ( not too bad with 2 kids and a blind dog)plus as you say approx 2 mins per contour but when we are out letterboxing we seem to travel at about one mile an hour if you include the time taken looking for the boxes. I am not sure whether it is the fact we spend to much time walking back and forth due to my lack of ability getting the bearings to meet or we spend a long time stamping up. But we definately spend more than 2 mins each at the boxes.
