A British man has finished a 28-year walk around the world. Karl Bushby, 57, started his adventure in 1998 in Chile. He walked home without using cars, boats, buses, trains, or airplanes. He travelled 58,000 kilometres through 29 countries. He crossed deserts, mountains, and jungles. He met polar bears and kidnappers, and spent time in a Russian prison. He had problems with money, visas, and borders, so his trip took longer than he planned.

Thousands of people welcomed Mr Bushby home. He was happy to finish his journey. His mother greeted him outside his home. He spoke to the crowds. He told them he could not have finished his trip without the help from people around the world. Britain's leader congratulated him. Bushby said he wasn't so interested in walking. He said: "It's boring as hell." That didn't stop him crossing four continents. A movie will be made about his adventure.
