Is it interesting? For non climbing audience

{In the Italian Alps, a frightened American kid is pushed to learn how to ice climbing.}
———————————————————————————————————
It’s hard to say if the story would be interesting to non-climbers because your logline (As written) is not yet a story: It is more of a situation.

1: A story needs a lead character… Frightened American Kid (So we have a lead character in your logline)

2: Then something happens, this is the inciting incident… We don’t at this point what that incident is; what causes the kids to go to the Alps in the first place. (This event is very important for a logline to have)

3: The inciting incident causes the lead character to have a goal… Again, we don’t know what’s the goal of your lead character. (A goal is a must for a logline, without a goal there is no story)

4: Then there is something or someone standing in the way of that goal… You say the kid is ‘pushed’ but fail to tell us who is pushing the kid… This would be the antagonist. (Story is conflict, telling us who is standing in the way of the kid’s goal is a must for the logline)

Anyway, once these elements are added to the logline, the logline will be far more likely to hook the reader.

Finally: A logline isn’t really about finding out if a reader is interested in the story. It’s about selling the story to the reader.

A logline condenses your story to its basic elements in a compelling way that forces the reader to sit up and take notice.
So when you write a logline, you should think like a salesman not like a survey taker. (And like anything it just takes practice)

Hope this helps.
