The men's 300m world record was set in 1994 by Michael Johnson in Indianapolis, USA, with a time of 32.60 secondsThe women's 300m world record was set in 1998 by Marita Koch in Munich, Germany, with a time of 37.18 seconds. These records are all set in good venue conditions and have a high degree of authority and recognition. 
However, with the passage of time and the advancement of technology, records have been broken in track and field competitions, including in the 300m race. The men's 300m world record was broken at Sydney 2000 when France's Maurice Green clocked 31.97 seconds. The record stood for 16 years until it was broken by Great Britain's Craig Whiteman in Rio on 15 August 2016 with a time of 31.87 seconds. The women's 300m world record was broken in 2005 by Sandra Perkova of the Czech Republic with a time of 34.85 seconds. 
These new world record holders not only possess exceptional physical fitness and athletic skills, but also take full advantage of modern technological advances. For example, they use high-tech running shoes and training equipment, and use scientific methods and techniques in training and competitions, which provide strong support for them to achieve better results in competitions. 
In addition, modern sporting events are increasingly focusing on the conditions of the playing field. Good field conditions can create a better competition environment for athletes, reduce the interference of external factors, and allow athletes to better play their strengths. Therefore, with the continuous improvement of field conditions and the advancement of technology, we have reason to believe that the world record in the 300m race will continue to be broken in the future.
