I took a yoga class earlier this morning and my Forerunner would not permit me to turn the timer off. The only way I got it to stop was to Sync it. Lost the data from my yoga workout and now I have to buy a new watch. I entered the data manually but good old Garmin gave me no credit for the Yoga even though you can clearly see that my heart rate went up. There product broke and they are punishing me. Good old Garmin. I have a race today and have to do without a working watch. Thanks Garmin. MTHepler
