Michael Johnson net worth: Michael Johnson is a retired American sprinter who has a net worth of $7 million. Born September 13, 1967 in Dallas, Texas, Michael Johnson is famous for winning four Olympic gold medals and eight World Championship gold medals. From 1999 to 2016, Michael held the the world and Olympic records in the men's 400 meter. He lost the record when Wayde van Nirkerk ran 400 meters in 43.03 seconds at the 2016 Rio Olympics. Michael still holds the current world's best time at the 300 meter. Johnson is widely considered one of the greatest and most consistent sprinters in the history of track and field. At the Atlanta Olympics in 1996, he won both the 200 meter dash and 400 meter dash events. During his career, Michael won eight gold medals at World Championships. He is currently tied with Carl Lewis and Usain Bolt for the most gold medals won by any runner in history. His stiff upright running posture and short steps defied the conventional belief that a high knee lift was paramount for maximum speed. As of today, Johnson still holds 13 of the top 100 times for the 200 meter and 27 of the top 100 times for the 400 meter. He also broke 44 seconds for the 400 meter 22 times, which is more than twice as many as any other athlete. After he clocked 19.32 seconds when breaking the 200 meter world record at the 1996 Olympics, Johnson appeared in Nike television ads and was billed as the "world's fastest man." Johnson served as one of the Olympic torch-bearers in the relay up to the London 2012 Olympics, carrying it to Stonehenge and Salisbury Cathedral in Wilshire.
