I think anything under 30 seconds is pretty good.
a good time is between 1:07 and 1:00. My time currently is 1:06 about. I am 13 and I swim year round though. Your time is really good.
I would say a low 15 to be competitive even maybe a 14 to win.
There aren't usually records in the 25 freestyle because after you turn 9, you never swim it again.
A good time would be 29 seconds.
A Good time would be :56-58 for 15 year old guy, a great time would be 0:50-52
27 seconds is a great time for a 50 freestyle. your time also depends on wether your a competitive swimmer or not if you are not you should be! dats a pretty good time! check usaswimming.com for the a, aa, aaa, aaaa times if your a competitive swima!
My son is 9.5 years old and does 21.5 seconds, he is pretty good at his class
A 23min 5k would be an ideal time for a 14 year old girl who has been running for about 2 years. If you are a beginner, 27min is a good time to start on. !
