Running Index on RCX5
Before training make sure you select running type sport on the training computer. This is needed to calculate Running Index together with speed and heart rate data.
After training you will see Running Index both in Data → Training files on the training computer and in polarpersonaltrainer.com web service after data sync.
If you have had any abnormal heart rate readings
at the beginning of the exercise, Running Index may fail even if heart rate measurement has worked fine during the rest of the exercise.
You can stop the run only once if you want your running index calculated.
