How Long Does It Take to Walk 100 Km By Age And Gender?

I spent 34 hours walking the last 100 kilometers of the Appalachian Trail, from Smithsburg, Maryland, to Boiling Springs, Pennsylvania (approximately 108 kilometers), resting for about 5 hours to sleep. That was, however, after nearly six months of daily walking.

However, it takes most people between 20 to 25 hours to walk 100 km. If you walk at 4 km/h, you will take 25 hours, and at 5 km/h, it takes 20 hours. It is noteworthy that undertaking a 100 km walk without any rest in a single stretch is not a feasible or secure option for the majority of individuals.

Walking 100km is no small feat, and it’s a challenge that many people choose to take on. Whether you’re doing it for fun, for a charity walk, or as part of a pilgrimage, it’s important to have an idea of how long it will take to complete the distance. Many factors can affect the time it takes to walk 100km, including the terrain, weather, and the pace at which you walk.

How long are 100 km? 100 km is equal to 62.13 miles and 328084 feet.

Breaking Down the Distance

If you’re planning to walk 100km, it’s important to plan your journey and break down the distance into manageable chunks. The table below shows how many days, how many hours a day, and how many kilometers a day you need to walk to reach 100km based on a walking speed of 5 kilometers per hour.

A more acceptable expectation for someone who hasn’t done much walking but is in good health and physical shape is to do it over 5 or 7 days.
