yes, a 15 year old sprinter with great talent can run 100m in 10.9 and 17 year old could run a 10.5 but these are national winning times and 10.9 for a 15 year old is probably a close to a national record.
How do you run 100m faster?

As a 100m runner i think we can do something like 6.8 on the 60 but not less then 11 on 100m!
