I have to thank you.I dunno, I skipped 9.0 (long story). But doesn't seem like the kind of thing that would be added with a point update.
Open Fitness app on your iPhone, locate your workout, tap on it to see workout details, scroll down until you see Heart Rate, then tap Show More.
I was wondering if I could find a map of my journey, and doing what you said answered my question.
So much information in the Fitness app.
