A sprint that is 200m(or half a lap).
it depends on the age group. 15 seconds is a decent time for a grade school 100 meter dash, but it would be a decent time for a high school 200 meter dash.
100m - 9.69s 200m - 19.30s
Alyson Felix (USA) in 21.88s
Usain Bolt and Allyson Felix
around 28 or 29 seconds
John Regis (19.87A) and Kathy Cook (22.11).
Nobody has broken 19 seconds in 200 meters yet.
Yeah that's a decent time especially since at 13 you probably aren't able to sprint the whole time. Yea that's state in my school, which is AA in Illinois. I ran a 27.3 on my state 4X200 team, sadly we got 32/35.
