Due to the -20something tomorrow, I'll have to run 14 on a treadmill. So I ran 5 on a treadmill today to get used to it, and the Vivoactive was pretty accurate. The last time I tried a treadmill with my phone and Nike+ I was something like .1 off every mile. The only thing I noticed was that I ran at 7.2 for 4 miles, and slowed to 7.0 for the fifth mile, and the GPS didn't really adjust to such a small change, and so it was a little off at the end (0.03).
I still hate treadmills. But sometimes you have to be smart.
