Ghosts of Buxley Hall is a Disney movie from 1978. The plot involves girls being admitted into an historically all-boy military-type school. There is an action sequence where the boys and girls are racing each other climbing "suicide hill" which is more or less a rocky embankment. The leader for the girls appears to be in her late 20's wearing a red top, blue jeans and white Tretorns with a blue stripe. You don't really notice the Tretorns until she starts climbing the hill given the length of her jeans.
Everyone scrambles to the top of the "mountain" with the boy leader getting there first. He zip-lines back to the bottom with no issue. The girl leader takes her turn with the zip line and just as she nears the bottom, her line catches causing her to fall off and land butt-down in a huge mud puddle. She is covered head-to-toe with a dejected look on her face.
Of course, she managers to pull the guy in and then scrambles to her feet and slogs out which is where the scene ends. She's never seen in the Tretorns again.
