How Long Does It Take to Walk 100 Miles? – (Complete Answer)

Whether it’s for fitness, personal challenge, or to savor the beauty of nature, many people find themselves asking, “How long does it take to walk 100 miles?” This isn’t a straight forward question as the time can vary significantly depending on several factors, including the individual’s pace, topography, rest intervals, and overall fitness levels.

This article aims to provide an estimated timeframe and factors to consider when planning to undertake this lengthy trek.

Calculating: How Long Does It Take to Walk 100 Miles?

Calculating the time it takes to walk 100 miles depends on several factors, primarily your walking speed. The average walking speed for humans is about 3 to 4 miles per hour. If you maintain a consistent speed of 4 miles per hour, without taking any breaks, it would take you 25 hours to walk 100 miles.

However, this scenario is highly unlikely because it doesn’t account for necessary breaks for rest, meals, and sleep. If you walk 8 hours a day at an average speed of 3 miles per hour, it would take you roughly 4.2 days to walk 100 miles. Keep in mind these calculations are estimates and actual time can vary based on individual pace, terrain, weather, and physical condition.

Factors Affecting Walking Speed

  • Fitness Level: The better shape you’re in, the faster you will likely be able to walk. Regular walkers or fitness enthusiasts can often sustain higher speeds.
  • Terrain: Flat, paved surfaces allow for faster walking than hilly or rough terrain.
  • Weather Conditions: Harsh weather, such as extreme heat, cold, or wind, can slow down your pace.
  • Walking Equipment: The type of footwear and any additional equipment like hiking poles can impact speed.
  • Rest Breaks: The frequency and length of breaks for rest or meals will affect overall walking speed.
  • Individual Factors: Age, height, weight, and personal health conditions can all play a role in walking speed.

Tips for Walking 100 Miles

  1. Training: Begin training several weeks before the walk. Start with shorter distances and gradually increase the mileage. This will help condition your body for the long journey ahead.
  2. Proper Footwear: Wearing comfortable and well-fitted shoes is crucial. Choose shoes that provide good arch support and cushioning to prevent foot injuries or discomfort.
  3. Pace Yourself: Do not start too quickly. Maintain a steady and comfortable pace to conserve your energy for the entirety of the walk.
  4. Hydration and Nutrition: Keep yourself hydrated and nourish your body with balanced meals and snacks. Consuming foods rich in carbohydrates and proteins will provide the required energy.
  5. Rest: Take brief rest breaks during your walk to stretch and relax your muscles. Also, ensure you get a good night’s sleep before the day of the walk.
  6. Listen to Your Body: Pay attention to any signs of discomfort or fatigue. If your body is signaling that it’s time to stop, it’s essential to heed that warning.


In conclusion, the time it takes to walk 100 miles can vary greatly depending on a multitude of factors such as your walking speed, terrain, weather, and how many breaks you take. Averagely, a brisk walking speed of 3.5 mph would mean that it could take approximately 28-30 hours of non-stop walking to cover this distance. However, it’s essential to remember that this is a significant physical and mental challenge, and preparation is key.

Take into account your personal fitness level, plan for rest and meals, and ensure you have suitable equipment and clothing. Remember, it’s not just about the destination, but the journey too. Every step you take is not only a physical achievement but a testament to your mental resilience.

So whether you’re walking 100 miles for charity, for a personal goal, or simply to test your limits, keep putting one foot in front of the other, and you’ll get there.
