This isn't really what you're asking for, but I used a podcast for couch to 5k. Podrunner: Intervals gives you each of the runs you need to get to 5k and changes the music up when you're supposed to walk/run. You could listen to that and just track along with the Workout app on its own.
Thanks for this. I grabbed at 38mm Nike+ Edition (black band) yesterday at Best Buy ($70 off in a sale) and was surprised that it seemed none of the couch to 5k options would work without taking the phone with you. Odd since they're just time-based intervals. So I just used that and tracked with the Nike Run Club App.
I'm loving the watch so far, despite a few hiccups. Namely it was a super pain to get those MP3s synced. It would just get stuck on sync pending, or say syncing and never start the percentage indicator. And yes I had it on the charger.
Eventually just found some posts saying to just reset phone and watch and un-pair and re-pair watch and it worked first try after that. So hopefully that's sorted.
I also get some drop outs with my Bluetooth headset (Senso Active Buds S250). I'm guessing it's just interference (near tons of houses and apartments so tons of wifi etc.), but annoying since they work fine with my phone in the same running route. With the Apple watch it's fine when running with my wrist around my waist, but I get some drop outs when walking with my arm extended at my side.
Anyway, overall I still dig the watch a lot. Worst comes to worst I'll just wear my water belt or a fanny pack on runs and stick my phone in there. I was hoping to not have to lug the phone, but Series 2 still seems more useful when paired with phone rather than used alone I guess.
The Nike Run Club App seems great so far. Easy to read even in the sun, I like the achievements and tracking of personal bests etc. I'm not sure about all the coaching options, how good those are, if they work without phone etc. Honestly don't know that I'll use them as even when I was running 5Ks and 10Ks semi-regularly I didn't really bother with speed workouts etc. and just didn't distance based buildups to races so simple run tracking is fine for me. Only missing feature is I wish it could display average pace instead of current pace as those estimates aren't that useful since they jump around a ton (same on my old Garmin Forerunner).
