> (In reply to Carpe Diem) Beware that most of the Garmin Forerunner series is easily damaged by water, an irony in a piece of kit intended to be used outdoors! I own a Garmin Forerunner 310XT which does everything, is brilliant and is fully waterproof!
I wouldn't say they're "easily damaged" - they're not suitable for lengthy immersion but rain or an odd short dunking won't do them any harm. They do have an official level of water resistance, which I think is up to 30 minutes in a metre of water - they don't recommend you swim in them, for instance. I've had FR305, 405 and now 610 and none have ever been damaged by rain.
Although...the FR405 can be a pain in the arse in the rain - the clever "touch" bezel goes wonky and won't respond. I ditched mine and got a 610 which I can wear as a normal watch - and is absolutely fine in the rain as it uses good old fashioned buttons.
There's an upgrade for the 310XT (not sure of the number - 6-something) but again it's too big to wear every day. I wanted something I could use as a watch as I kept forgetting to put my "running watch" in my bag.
I've not used my 610 on my bike as I have an Edge 800 for cycling, which is top notch - touchscreen sat nav and every possible bike computer function you could imagine (and some you couldn't).
