What's the best way? I've got an iPhone so I know there's a multitude of apps on there that can do this but the thought of running around with this thing strapped to my arm doesn't fill me with confidence nor do I want it jangling around in my pocket.
I've looked at some Garmin watches (forerunners) but they're best part of £100 each which is a little out of my budget.
So how does everyone track their runs? What's the best way (and most accurate) to do it?
