Twice my Forerunner 55 incident alarm went off. Once because of a minor mountain bike crash and the other for no apparent reason. Both times my wife received a text. I sent her text saying I'm fine. I would rather cancel it before it sends the text.
Yesterday I was zonked prior to the alarm and my heart rate was as high as 165bpm. I regularly get over 150bpm on rides easily. Also it was very hot upper 90s and high humidity.
Interesting after the alarm went off, for no reason. Because I was zonked I had a small crash and the alarm didn't go off. Do I need to reset it after the alarm has been activated? I think both times it went off the recording process stopped.
