Did you see this two nights ago? Amazing! The 400-meter world record was held by Michael Johnson of the United States, who covered the distance in 43.18 seconds on 26 August 1999. Johnson's average speed was 20.72 miles per hour. His mile pace was 2:53:72. Wayde van Niekerk of South Africa lowered the record to 43.03 seconds on 14 August 2016, which means Johnson's record stood for almost 17 years. Van Niekerk's average speed was 20.79 miles per hour. His mile pace was 2:53:11. I get chills watching the video. Katherine and I saw the race live on Sunday evening.
