I've been using a Garmin 800 for a while now. I use it with a HR monitor, cadence sensor and PowerTap power meter. Until today, no issues capturing all that info. Yesterday I got a vivofit. I was wearing it on my ride this morning. For some odd reason, my speed, distance and power did not register on the Garmin 800. I did get cadence, heart rate, and even calories. Weird. What is going on and how do I fix it? Should I leave the vivofit at home when riding my bike?
