Pause now really pauses.
Waiting at a crossing no longer ends your run. Tap Resume and your distance,
pace and splits carry on from where you stopped — and the time you spent
standing still is left out of your pace.
• A paused run offers Resume and Stop, instead of Start
• Your run is saved once, when you stop it, so one outdoor session is one
workout in Apple Health
• New dark route map
