What I am using to track my heart rate.

I can tell you this, if you want to take your outdoor workouts to the next level, the Mio Quest is the way to do it.  I have been using the GPS enabled watch for the past three weeks. It takes a little getting used to, but after looking over the instructions you will on your way, and out the door in no time.  The Quest has Waypoints, which are locations you can save.  After saving the location you can then rename it for easy access for locations you wish to return to later.  The watch uses chest strap to gather your heart rate too. 




I have been using to track my workouts, the Mio Quest.  The heart rate monitor with GPS is able to be downloaded and information can be then uploaded to MapMyRun.
