The Ghost runner feature helps you pace yourself during your run by setting a target pace for the ghost runner and showing your distance to the ghost runner along your run.
To use Ghost runner with Suunto 9:
Target distance or duration:
Optional setting. Adjusts a target distance in km or miles or a target duration for the run. This enables the finish time/distance estimate calculation during the run. Target is set in the sport mode options. The finish estimation is shown on the bottom row on the display during the run.
The Ghost runner insights also shows the following:
The lop left corner shows the target pace for current run as determined automatically based on first kilometer/half mile or by your latest manual lap average pace. Before locking your target pace in beginning of the run this field will show the average pace that eventually will become your target pace.
The top right corner shows your current pace.
The value in the middle shows the distance to the virtual Ghost runner that is moving with the determined target pace. A positive value means that you currently are ahead of the virtual Ghost runner.
