    With these charts, you should be able to do a rough estimate of how long it will take you to walk a given distance at a fitness walking pace without making stops. You'll have to add in more time if you have to wait at intersections for the crossing signal, make rest stops, stop to take photos, play Pokemon Go, etc.

    Distance, Pacing, and Finishing Time for Organized Walks

    You can also see how to measure or calculate your pace to find your time and distance at different paces beyond these rules of thumb.

    If you are entering an organized race or event with a finish cutoff time, use these methods to predict your finish time.

    It's important that you only enter events that you can complete them in under the time limit. It's also good to know when to meet your family and friends who came to cheer you on or catch a ride back home.

    Training to Walk Different Distances

    You may wonder whether you need to train to walk these distance. It's always a good idea to build up your walking time steadily from shorter to longer distances. See how far a healthy person can walk with no training, plus how far can you walk in eight hours if you're a trained walker.

    By steadily adding a longer walk each week, you will build your muscles and stamina. You will also toughen the skin on your feet, which helps prevent blisters. Start with the distance you are able to walk comfortably. Add a mile to that distance each week, which will be between 15 and 20 more minutes of steady walking. See the 30-Day Quick Start Walking Plan to begin building your walking mileage, whether you just want to walk a mile or you want to enjoy a 5-kilometer charity walk or even begin training for a half marathon or marathon.
