Around the 50-minute mark of my workout run today, during the cool-down period, my music stopped, and when I glanced at my watch, I saw the blue triangle, then some words. After a minute or so, I was given the option to save/resume the run. I resumed, and the watch continued to count time and mileage (gps re-connected a few seconds later), but the programmed workout didn’t resume.
After I finished my run, the data looked fine, except the exercise load showed as 15, and the run was classified as recovery — clearly wrong, based on many years of prior runs. I checked to see if the reset had somehow changed my heart rate zones, but that info looked fine.
No prior problems with the watch, so I guess I’ll assume it was a one-time glitch.
