If you earn a 1 mile PR on a half marathon run, is there a way to find out where the 1 mile PR happened? The PR time doesn't match any of my 1 mile splits, so I'm assuming it crossed split times.
You could set up a free Endomondo account and sync. it to your Garmin account.
In Endomondo, you can see all the best distances for each run and have them highlighted on the map by hovering your mouse over them. I use that all the time.
Thanks! I did exactly that, and can now see my best times for 1 mile, 3 miles, and half marathon on the map.
I had to export the workout from Garmin Connect as a .gpx file and then import it into Endomondo, since connecting the two accounts together only works for future workouts. But after that, I was able to view the workout in Endomondo, select the "Best distances" tab just below the map, and see the data.
