Any way to display miles and km times in my results?

Well, not directly, but there is a rather simple workaround. Assuming you already have the auto-laps set up on your watch to 1 mile, and can see the mile laps on the screen by default. For the 5 and 10 km laps (or any other distances you wish), you can get the info in the following way:

1. On the concerned Activity screen select Trim Activity from the cogwheel menu (in the top left corner)
2. On the Trim screen, click the tab Distance
3. Enter Total Distance 5 km - the time and pace will appear instantly at the top (if they don't simply click on the white space of the page)
4. Repeat for 10km or any other other distance you are interested in. You can also set the Trim Start value, if you want to skip some part (i.e. the warm-up part)
5. When finished, click Cancel to come back to the original activity without trimming it at all
