How do you know how far you have walked? There are several ways to measure your walking distance, with more available than ever before thanks to mobile apps, GPS and computer mapping.

Map and Measure Your Walk Online

You can lay out routes using MapMyWalk online. The website allows you to draw the routes and get a distance reading. MapMyWalk has both street view and satellite view. You can zoom in on portions of the route that use a sidewalk or path that isn't along a street.

With a premium subscription, you can print out maps and directions and export them to your phone app to use while walking.

Mobile Phone GPS Apps for Walking Distance

In the ancient past (just a few years ago) you needed a special GPS unit to measure walking distance via satellite technology. But now the GPS in your smart phone and is used by many apps for smartphones that can track your speed and distance, such as MapMyWalk. It couldn't be more convenient, since it's likely you're bringing your phone along on your walk. Besides knowing how far you've walked, you can also see the route you've taken, which can help you navigate back to where you started.

Many smart pedometers, such as Fitbit, are linked to apps that have an exercise-tracking function that will use the phone's GPS to map and measure your walk.

The accuracy of the GPS distance depends on several factors. If your phone loses contact with one or more satellites, you can see a sudden jump in distance.

You can expect the distance to be off by as much as 10 percent, especially in areas where you don't have a clear view of the sky. Plus, it often doesn't work well indoors and won't measure your distance on the treadmill.

Sports GPS Watches

Garmin, Tom Tom and others make GPS watches for runners and cyclists that also work for walkers.

These often display both your speed and distance and may link with heart rate monitor straps or have LED pulse detection built in. They may be more convenient for checking on the fly compared to your mobile phone app, but they are fairly expensive.

Wheel It

You can drive a walking route in a car or on a bike with an odometer and measure it that way. The distance may be off depending on whether your odometer is properly calibrated for your tire size and other factors. The gold standard for walking events and running races is to use a mechanical wheel that clicks off each yard or meter.

Pedometer Distance

You can translate pedometer steps into distance if you know your stride length. Many pedometers ask you to measure your stride length and enter it into your user profile, then it automatically calculates distance. For this to be reliable, you need to have a very consistent stride. I use the pedometer distance reading only to get an estimate and don't rely on it as an official reading.
