Based on what I've seen at a local running club with 60+ members, most regular runners seem to have picked up at least one wearable (although I haven't seen that many Apple watches - most have gone for either Garmin or TomTom). In fact, I'm certainly in the minority as someone who hasn't.
That said - the more professional members are generally also in that minority too - they tend to stick to using their phone or they don't bother tracking their runs at all.
