Dude...honestly...I'm going to look it up on USA swimming right now...but I think I swam faster than that when I was 10 and and been swimming for a couple months.
EDIT: alvino, you go 56 long course meters? That's pretty quick, converts to like 48 short course yards.
When I was 10, I went 1:17.00 in the 100 yard freestyle, the first time I ever swam it. That converts to a 1:29.22 in meters. So I beat him by a solid 23 seconds.
