Describe usage of the "Workout Only" mode

[gdoumen]

Since UI release 0.9.40, it is possible to perform a workout without selecting a route (or free ride)

The way it works:

• User opens the workout area
• User selects a workout
• In the WorkoutDetails dialig there is now a new Button "Start without route"
• Clicking this button will immediately start the workout. The screen during the ride will show the ride/workout dashboard and a graph showing actual power and heartrate data compared to the workout
