Both those controllers need to talk to each other.
There are a few ways, but I would go with a common class object.

Think of the controllers as dumb views that only show information and send interaction events (think MVVM but we're not taking that pattern now).
Let the real workout logic reside in a class object that you share between the 2 controllers.

Example:

class WorkoutManager {    
    var workoutStarted: Bool = false

    func startWorkout() {
        workoutStarted = true
        //...
    }

    func stopWorkout() {
        workoutStarted = false
        //...
    }    
}

Open Group related code:

//Common object to be sent to both controllers
let manager = WorkoutManager()

WKInterfaceController.reloadRootControllers(withNamesAndContexts: 
    [(name: "page1", context: manager as AnyObject),
     (name: "page2", context: manager as AnyObject)])

In Both Controllers (Very Important):

var manager: WorkoutManager!

override func awake(withContext context: Any?) {
    //...
    self.manager = context as! WorkoutManager
    //...
}

Page 1 related code:

if(manager.workoutStarted == false) {
    manager.startWorkout()
}
else {
    manager.stopWorkout()
}

Page 2 related code:

func startworkOut() {
    manager.startWorkout()
}

func stopworkOut() {
    manager.stopWorkout()
}

This WorkoutManager is just an idea on how to proceed. It should surely contain other content that you want to show, like the heart rate and distance.
Best of luck
