Apple Watch with Spotify and Nike Run

I am thinking about getting an Apple Watch and want to be able to take it out on runs and use Spotify and the Nike+ Run app without having to carry my phone. At the moment, would rather get the GPS Apple Watch, and not get the cellular+ one. Does anyone know if I can use both of those apps on the go without having my phone nearby and still have just the GPS watch? I was thinking that I would be able to get buy with the Series 3 GPS watch and be able to go on runs without my phone, but I wasn't sure. I don't need any special features, other than the ability to connect to Spotify and Nike Run, so the features on the newest models (like the ECG and blood oxygen apps are not necessary. Thanks for your help!
