So Ive been using my apple watch nike run club while running on the treadmil using the coached guided runs. I want to be able to start the run on my iphone so it keeps track of the run on the iphone and watch but I dont want to have to hold my phone in my pocket while running. If i dont have my phone on me while running as i put it down the run is not being tracked of how far i am going. Am I doing something wrong here.

Here is the support site for the Apple Watch and iPhone use together and separately.

Usually with an Apple watch Version for 3 +, you don't need your phone with you for the watch to work coherently.

You just have to make sure the settings on the watch and the phone are correct and it should work perfectly.

Like starting it from the iphone that way you dont haveto download the runs to the watch.

If you start the app from the app in the watch, the status should work for it through the app on the watch.

I used this when I use to run using my watch and it worked just fine using my Version 1 watch.

This is correct. If you want to have your phone on your person I’d recommend a fitness case where you can attach a strap.
