No it is not very healthy considering 20km is almost 12 miles and walking 5 miles a day is considered very active. Your body, joints, muscles, and nervous system need rest time and you dont need to walk 20km a day. I recommend you reduce 20 km to maybe 10 km at most and dont walk every day.
Additionally, can I walk 20 miles without training? Having said that, its not necessary—or advisable—to walk longer than 20 miles in training. Some walkers figure that doing 23 or 24 miles in training will help them to build confidence. Maybe so, but every mile you walk over 20 in training increases your likelihood of injury and adds to your recovery time.
Similarly, it is asked, how long does it take to walk 19km?
As a baseline you could use 1 km an hour. At this pace it would take you 17 hours to walk 17 km. However that is obviously an extremely slow pace. Take a more realistic walking pace such as 5.5 km/hour (around 3.5 miles/hour) and it would take you about three hours.
How do you calculate walking time?
His rule is: Walking time = 3 miles per hour.
These parameters are:
Walking time = 2.5 miles per hour. Climbing Time = 1 minute for every 10 metres ascent. Descent Time = 1 minute for every 25 metres descent. Breaktime = 1 minute per Breaktime minute.
