I have had a good Google and look through the forums but can't find an answer. I currently use my Samsung Galaxy Note 2 to record rides/runs on Strava. I'm not in any serious training regime at all, but I like to keep a track of what I'm doing and how I am 'improving' I use a Zephyr HxM heart rate monitor with it and obviously have the GPS on. I know the phone has a barometer but, because I use a waterproof pouch while out, I'm not convinced the barometer is getting accurate readings inside the sealed pouch. Also the Note 2 is a big phone to be taking out regularly.
I've considered getting a smaller Android to put my SIM into while out, but that would still potentially have problems with the barometer. I've looked at some Garmin devices and because I also run I as looking at the Foreunner 310XT which has a quick release kit to switch between a wrist strap and a bike mount. Does anyone have any experience of using this Garmin device at all or know how accurate it might be?
