The simplest pedometer merely records the number of steps you take, but more sophisticated pedometers have additional functions. Many pedometers can also estimate the distance you travel during your walk or run. This function typically uses your average stride length, which you must input into the pedometer. You can measure your average stride length with a pedometer if you have a walking or running course with a known distance.
Step 1
Choose a course for which you already know the distance. This should be a course with the same slope as the one you typically use. A standard 400m running track is ideal if you typically run on a level course.
Step 2
Determine the exact distance of your course. The circumference of a running track depends on the track that you use. For example, the circumference of lane one is 400m. The circumference for lane two is 407m, lane three's circumference is 413m, and so on.
Step 3
Reset the counter on your pedometer to zero and wear the pedometer according to its instructions. This generally means placing the pedometer near your hips, so the pedometer records a step each time you pick up your legs.
Step 4
Walk or run around the track one time. Stay in the same lane and maintain the same pace you typically use while exercising.
Step 5
Compute your average stride length. This calculation uses the equation (course length) x 39.37 / (number of steps) where course length is in meters. This formula will provide your average stride length in inches, which are the units that most pedometers use. Assume you took 425 steps in lane one, which has a circumference of 400m. Your stride length is 400 x 39.37 / 425 = 37.1 inches.
