1. Start a session
Once you've installed the iOS app, Nike+ Running will show up in your Apple Watch's menu, from which you can initiate a session.
Swiping in the app before selecting a new session shows you the average number of miles of your last 10 activity sessions and how many of your friends have completed the circuit if it was a public track.
If you want to start a new session, tap Run.
2. Track your run
Put away your phone (but be sure to take it with you for the GPS mapping to work) and from here you can check on your exercise options from the convenience of your wrist.
Whether you chose running or cycling you can now keep track of live statistical data, including pace, distance and time elapsed. This readout is especially accurate since the Nike+ app senses if you stop moving and pauses.
3. Get motivated
Glances at your Apple Watch let you get a quick view of your friends leaderboard so you can motivate yourself to keep up. You are also able to receive and send cheers to fellow runners while in session, and if you've got Bluetooth headphones paired with your Watch you can listen to music from iTunes.
GPS maps also reflect the intensity of your session using colour.
