The Earth's Circumference
The Earth's equatorial circumference is approximately 40,075 kilometers (24,901 miles). However, walking routes would be longer due to terrain and obstacles like oceans and private property.
Average Walking Speed
An average walking pace is about 5 kilometers (3.1 miles) per hour on flat terrain. Individual speeds vary based on fitness, terrain, and conditions.
Continuous Walking Time
Without obstacles, walking non-stop at 5 km/h would theoretically take 8,015 hours or 334 days to circle the Earth along the equator.
Real-World Considerations
Factoring in sleep, rest, and food, it could take a person approximately 4-5 years to walk the Earth's circumference, assuming perfect conditions and routes.
Historical Attempts
Jean Béliveau walked around the world, taking 11 years from 2000 to 2011. His journey was over land and included significant detours, diversions, and challenges.
Environmental Challenges
Walkers would face diverse climates, from Arctic cold to desert heat. These conditions would significantly slow progress and require careful planning and resources.
Physical & Mental Strain
Long-distance walking presents extreme physical and psychological demands. Few people have the endurance, willpower, and logistical support to undertake such a journey.Fastest Human Walk
The fastest recorded walking speed for a human is 15.7 km/h (9.8 mph) by Yusuke Suzuki in 2015.
