I recently took a fitness test on a treadmill. Although I was wearing my Garmin HRM, it is an older model that uses only ANT+, but the treadmill uses Bluetooth only. Since the test requires heart rate data, I used the treadmills hand grips heart rate monitor. Since this prevented me from swinging my arms, my Forerunner 220 was unable to sense cadence data.
I uploaded the data from the FR 220 to Garmin Connect web, and then edited the data using results from the treadmill. But, I couldn't save the data without entering SPM (Strides per minute), both average and maximum.
Garmin Connect didn't have SPM data before the edit. if I don't have SPM data, why should Garmin Connect force me to make up some numbers? Why can't it remain "Not available" ("N/A") ?
