Request #126

 I read a YA thriller/romance from my elementary school library – probably in about 1970/1972 – about a girl who is 16? and a competitive ski racer. She comments on carrying extra weight and how it helps cut the wind resistance in competition. She comes across some spies in a mountain hug while out on a trail, and winds up helping them (intelligence agents ), and develops a romance with a young man who’s one of them towards the end – also rescues him from danger. I would love to know the title! Something with “wind” in it, possibly?
