Field pacing is a brisk, equipment free way to measure distance.

How to Measure Your Pace

Measure a known flat distance (e.g., 100 ft or m). Walk it while counting your steps (either every step or every two steps). Repeat and average your count. Divide the distance by the average steps to get your pace length. For unknown distances, count your steps and multiply by your pace length.

Divide the known distance by your average pace count. This gives you the length of one pace (e.g., 100 feet / 45 steps = 2.25 feet per step).  
Measure Unknown Distances: Walk the unknown area, count your paces, then multiply by your pace factor (e.g., 20 steps * 2.25 feet/step = 45 feet).
