well im the fastest 15tn year old in Renfrewshire and thts got more than 1000 15tn year olds with a time of 12.4 seconds ( i think ) but when i was 13tn my time was around 13 seconds so i think thts a gd time
the answer would be around 11.90 - 13.90
i ran 12.92 and i hold my regional record but that's about in the middle so yeah.
probably 13-13.5 seconds :)
13-15 secs. if you are very sporty you should be looking for 13secs or quicker.
13-15
13 - 13.5 seconds
That's a fair time.
11.25 seconds
9.58s for men and 10.49s for women.
Three seconds on the 100m dash!
Usain Bolt with 9.58s
around 30 seconds
Florence Griffiths-Joyner with 10.49s.
I do 14:89 but 15 or 16 seconds is also good
14. 56 is a good time
9.57 was mine
A fast time is probably 16 or 17 seconds!:)
