You can use more than one tool. I have a Garmin and use an HRM strap. I upload to Garmin Connect (automatically by Bluetooth) and Strava when I come in. I connect with different people on each. JP (poster child) and Chris (CJT1217) from FS are on Strava. I've done a NY Rock 'n Roll. They're well done. What about ING on Nov 3rd?
