How long would it take to walk around the entire world?

Walking around the entire world is a massive undertaking. The Earth's circumference at the equator is approximately 24,901 miles (40,075 kilometers).

If you were to walk this distance at a steady pace of 20 miles per day without stopping, it would take you about 1,245 days, or roughly 3.4 years.

However, in practice, a trip like this is much more complex:

• Geography: You cannot walk in a straight line around the equator due to oceans. You would need to take routes that cross land bridges or rely on ships, which adds significant distance.
• Terrain and Climate: Mountains, deserts, and extreme weather would frequently slow your progress.
• Rest and Logistics: No one can walk 20 miles every single day for years without breaks for health, supplies, visas, and recovery.

People who have actually completed "around the world" walking expeditions—which generally require walking a minimum of 18,600 miles (30,000 km) on at least two continents—typically take anywhere from four to over ten years to complete the journey.
