For the average 14-year old boy, I would say the average 50m free time would be about a 29.40 sec.
A good time would be 29 seconds.
what is the average running time for a 52 year old female.
My 8 year old son just swam it in a minute and 5 seconds
There really isn't an average time because it varies about how fast people are. But I would say around 59.999 seconds?
