The average 200m running time for an 8th-grade student in the United States typically ranges from 27 to 30 seconds. This time frame reflects a combination of factors including physical fitness, training, and individual athletic ability. According to the National Federation of State High School Associations (NFHS), the average 200m time for high school athletes is around 25 seconds, suggesting that 8th graders are generally a few seconds slower. However, individual times can vary widely, with some 8th graders running as fast as 24 seconds and others taking over 35 seconds. The variation is influenced by factors such as genetics, training regimen, and overall physical development. Research indicates that the 200m dash is a good indicator of an athlete's speed and power, making it a valuable measure of athletic potential in younger age groups.
