The 2004 Olympic gold medalist in the 100 meter dash was Justin Gatlin of the United States in a time of 9.85 seconds.
Two sports come to mind when I see the phrase "100 yards long". One is the field of play in American style football. Both college & NFL football. Excluding the 10 yard end zones, the regular field of play is 100 yards long. Also, in high school track, the old 100 yard dash is still an exciting event. A good time for high school kids in the 100 yard dash is 9.5 seconds. An average time is around 10 seconds.
100 meter dash, 200 meter dash, 400 meter dash, 800 meter run, and the 1500 meter run.
It orginated fro mteh Ancient Olympics.
The 100y is rarely run outside the US, however, it is likely that Bolt will have passed the 100y mark in his best 100m race in around 8.75s.
14. 56 is a good time
a 11.9 and lower is a good time
To me a good time would be 14-15 seconds.
A reliable way to convert a hand-held 100-yard time to an electronic 100-meter time is to multiply the hh-time by 1.103. Therefore, 10.2 in the 100-yard dash time equates to an 11.25 100-meter dash time. Also, to convert an electronic 100-yard dash time to an electronic 100-meter dash time, multiply the first time by 1.088. For example, a 10.20 electronic 100-yard time equates to an 11.10 electronic 100-meter dash time.
Around 13 seconds
If you are in the age between , 12-16 that is a very good time
I don't know, but my time was 13 seconds
The equivalent time for the 100 yards dash based on a 9.58 second 100 meter dash world record is approximately 10.44 seconds.
10.7 100 meter dash = 9.78 100 yards
For a high school level male, I would say 11 is pretty fair.
The 100 yard dash is not run in the Olympics but the 100 meter dash is. Frank Jarvis of the United States won gold with a time of 11.0 seconds in the final. He also ran a 10.8 second preliminary heat which tied the world record at the time.
A rough estimate would be around 4.3-4.4 seconds for the 40 yard dash when converting a 11.5 second 100 meter dash time.
