Perhaps...you could just go out and run?
Seriously. I've done multiple marathons, the Disney Goofy Challenge, a number of triathlons including two Ironman races, etc... You don't need all this fancy stuff. Just make sure you keep a phone with you (or your wife in this case) in case you have an emergency, bring ample water and snacks if you're out for long training runs, and enjoy the time. Get away from computers, TVs, phones, etc. Enjoy being outside. If you and your wife are running together, then enjoy the time together, working to a common goal, away from all of the hustle of normal life where everything is connected.
Running without all the crap is the best, most enjoyable, time for me. I love it. I used to run with music, GPS tracking, etc. Now, just a phone in case of emergency and sometimes not even that. Give it a try. You'll love it. And your wife will too.
