Asafa Powell was the world record holder with 9.77s, he subsequently run 9.74s.
Usain Bolt has recently run the 100m 9.39 seconds he did this at his training center in his home town Toronto, Ontario, Canada
David Ambler - 100m record of 10.41s
That was Tim Montgomery of the United States who ran a 9.78 in 2002.
Paul Nash 100m record was in 1968
Kristy Coventry from Zimbabwe rewrote the world record for the women's 100m breastroke, and the record is 58.77 seconds.
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.
