Ask Adrian: Our technology editor tackles your trickiest tech problems
Question: I've decided I want to train for a marathon next year. I want to get a decent sports smartwatch to help encourage myself. Is one of the tracker devices enough or is it worth getting one of the fancier ones? Would an Apple Watch do the trick? A friend of mine recommended a Garmin, is that any use? I'm not a tech expert but know my way around a smartphone well enough.
