80’s film unknown title

[Mum]

Hi I’m trying to look for a film I watched when I was younger in the 80 ‘s for some reason I have a tune about a song I think in film saying something like I got out of bed ? And it was roughly a family and I think it was about a girl who was a swimmer who was going to swim the ocean or something like tht any ideas I no it’s hard as I don’t remember what it was called or who started in it any help thankyou
