Between "document settings" and "application data" there's my user name on the PC.
After devices is a folder that's a ten digit number and after that a folder called "activities". Within that folder are the .fit files. Have her search on her PC for such a folder. Of course, she's then got to import them into a web page, or application that can read .fit files. Strava and Sporttracks definitely do. I expect most of the rest do too.
I've used Shoe Goo in the past, putting it on when the shoes were new at the two points that I new would wear. I had no physical problems running with it and it did give some protection to the shoe. Why did I stop using it? I felt that it wasn't the obvious physical wear that was the real problem, but invisible damage to the cushioning within the shoe. My current pair of Asics GT-1000 look fine, but each step feels harder than I remember that it used to.
Pros: you get to see bits of the destination that you'd probably not normally see and some are actually interesting; you'll find your way around easier as you've stared and stared at a map before you went and now you've actually run bits of the place; and (for me) I recognised that people are basically nice.
Cons: you get to see bits of the destination that you'd probably not normally want to see (a significant amount of the Tallinn race was along a motorway); you'll need to wash your kit in a sink in the hotel (I just got into the shower wearing mine); you can't eat and drink before the race like you'd normally eat and drink on holiday; and your partner is going to have to entertain themselves on the day and put up with your moaning about your muscles aching the next day.
