Patty Duke looks a bit like a dip when she's running to "the beat", but it's also a pretty decent little movie.
despite it also being a musical, with some of the schmaltziest songs ever.
on the plus side, there's a lot of truly funny lines, and the tomboy has a very supportive family when she joins the boys track team. heck, even the coach is on her side from the get go, and most of the boys are as well.
I saw this in the 70s, well after the E.R.A was started, so the movie was a bit ahead of it's time. it seemed to last a lot longer than it's the 90 running time though, and I don't actually remember the ending of the movie. it's odd, since it was shown on a kiddie matinee and I wouldn't have left the theater early, as far as I know.
Jim Backus is also a wonderful presence in the movie, being a good father despite being befuddled somewhat by the women in his life.
