Can You Walk 15 Miles a Day?

Would walking 15 miles a day mean walking for over 24 km? Absolutely! That’s quite a distance, but yes, you can walk 15 miles a day. You can opt for split sessions of smaller distances, or you could prepare for a single long walk.

Nevertheless, walking 15 miles requires preparations that will keep you from injuries, giving up along the way and other side effects.

Preparation for a 15-Mile Walk

Basically, 15 miles is long, and I have some tips that will prepare you for the hike;

  • A few weeks before walking 15 miles, ensure that you walk shorter distances at least 5 times a week. 5 miles a day will do, though you can opt for 7 to 8 miles a day for 3 to 4 days a week.
  • Go for walking gear; ensure that you purchase comfortable walking shoes which are breathable, moisture-wicking and fitting. Likewise, go for clothes that are non-chaffing and suitable for the weather if walking outdoors. Also, don’t forget weather-specific gear such as sunglasses during hot sunny conditions.
  • Add strength and resistance exercises to your preparation, with emphasis on lower body strength training.
  • Prepare a backpack where you can put your excess clothing in case it gets hot. The backpack is also more convenient for snacks and water.
  • Mark out water replenishment centers along the way to avoid carrying too much water and adding to your burden.

Side Effects of Walking 15 Miles in a Day

  • Fatigue and hypoglycemia
  • Sores on the active muscles and blisters on the feet and toes
  • Dehydration 
  • Irritation and a gloomy mood
  • Slowing or stopping too many times and for far too long
  • Inability to carry out other simple tasks after the walk
  • Muscle and joint injury requiring medical attention
  • Light-headedness and probable loss of consciousness in extreme cases

How to Avoid the Side Effects

  • Consider an appropriate time of the day to start the walk. For example, you can start early in the morning, at around 6 am, when it is still cool and easier to walk outdoors.
  • Choose softer stepping grounds such as grass as opposed to stones.
  • Since it is a long distance, you can start at a slow pace that will take you through without too much fatigue. You can also walk at intervals, combining some quick and leisurely sessions.
  • Take breaks to replenish your body with hydration and energy snacks. Ensure you take along enough to get you through at least two breaks, especially during your first walk.
  • Take a speedometer or a heart rate monitor with you to take count of your metrics; calories burned, speed, distance, and time. You may also need a map (physical or digital) if the path is new.
  • Keep yourself busy during the walk. The scenery may be enough to keep you occupied if it is a new place. However, if it is a familiar path, consider taking headphones for podcasts, music, e-books, or lectures to keep you from thinking about the long distance.
  • Slow or rest when you feel tired to rejuvenate for the rest of the walk.


It takes approximately 3 hours to 5 hours to walk 15 miles. The exact duration will depend on your speed, terrain, and whether you take breaks between the walk. While you might not walk the distance daily unless you are a professional athlete, it is a great way to stretch your body during holidays and favorable seasons.
