So my next question is will the Apple Watch GPS be as accurate as the Garmin?
I think the easiest way to start a running group may be to connect through Nike+ (since everyone with an AW will have access to it). For those that still se a Garmin to track their runs, they can link their Garmin accounts to Nike+ pretty easily (I do).
It's true that you can't see average pace (yet, I hope), but if you enable audio feedback you can get average pace after each mile. Ideally I'd like a lap (i.e.,1 mile) pace and average pace, but at least average pace is available by audio now.
I've tried several apps and basically none of them work reliably yet and are full featured. NRC and Workouts don't export to Strava, bridging software like RunGap only exports a high level overview of your activity and PEAR sports which records without the phone records one run and uploads very different numbers to Strava! Strava have said they're working on an update to their app but in the meantime I'm going to use the Strava phone app because potentially running a personal best and losing the data is no good to me
Based on the past several posts, it looks like I'll have to stick with Garmin Connect and Strava and skip the Apple Watch until they've figured out how to get data to sync properly with Strava.
