How long will it take to get from "Point A" to "Point B"? Estimating the answer to this question is essential for outdoor leaders to accurately and safely manage their outdoor adventure education course. By being able to carefully estimate the amount of time needed to travel a particular route, over the course of a day or an entire expedition, outdoor leaders will be able to avoid unnecessary risk and provide ample time for other experiences and curricula. This paper describes several land-based travel calculation methods (including the less known Munter formula recently added to www.caltopo.com's mapping functionality) and notes why they are essential for leading successful outdoor expeditions. Far from an effort to micro-manage course schedules to the second, this paper offers recognized techniques that allow instructors (and students) to calculate the duration of travel, thereby protecting other pedagogical interests through "a reverence for time."
