Yup Garmin Forerunner 620 and HRM here.. You using a Polar HRM? Easy enough to sync and how's the route mapping, you plug directly into USB? Thanks mate I use Garmin's own HRM-Run which tracks Cadence, Vertical oscillation and Ground contact time. The Forerunner connects directly to my phone and will sync to Garmin connect via bluetooth or wireless, then subsequently to Strava. You can connect via USB as well, and will sync fairly easily. All of the Garmin Forerunner range will connect via USB, some like mine do it wirelessly though. Is there anything your Garmin doesn't do that you wish it would? To be honest, my main concern is HR Zones at the minute, if I can glance and get myself % of MHR and my distance/pace I'm pretty much sold. Thanks for the info so far too mucker Not really, it cost me a bloody fortune! The HR zones are good, you can edit the screens to show you pace, average pace, lap, HR etc. The new one reads you heart rate from the watch on your wrist rather than needing an HR strap, which would be handy. This article has a good review of my watch.
