Swimming Doesn'T Doesn'T Depend On Size

I am 14 and I'm a swimmer. I'm not the biggest kids on my team but I don't care. Last weekend I was swimming verse the biggest kid on my team we were both aiming for the record. Everyone thought he was gonna beat me but no. He took the lead only for a 300 but them I caught up and passed him and then double lapped him. I ended up getting the record and size doesn't matter
