Fenix 5x + HRM Tri issue

Former Member over 7 years ago

Hey all. I was wondering if anyone has ever experienced this issue I'm having with my fenix 5x. So I have used it plenty of times on the treadmill(in treadmill mode) and it is usually fairly accurate. I just got the garmin HRM tri and began using that at the same time. The first couple of times I had no issues. All of a sudden when I run the watch registers zero mileage, it also isn't giving me the option to 'calibrate' after the run is over so I can't change that 0 to whatever mileage I just ran like normal. I have to go into Garmin connect/training peaks and edit afterwards and it's very annoying.

Anyone have any thoughts?

Thanks like always!

That is strange, speed and distance should be coming from the accelerometer in the watch, only running dynamics (I'm not sure about cadence) from the Tri, so wearing the Tri or not, should not have any impact on the distance. Do you use a foot pod? Are you wearing the watch as usual?

Cadence comes from "HRM Tri". In case of problem with "HRM Tri" - no cadence, no mileage.

Cadence can come from the accelerometer in the watch I do it all the time, Ground contact time and balance, stride length and vertical oscillation would require the HRM-TRI or what Garmin refers to as Advanced Metrics.

From DC rainmaker's Blog

Cadence comes from the following sources:

A) Wrist itself (in the watch)
B) HRM-TRI or HRM-RUN straps
C) Footpod (ANT+ or BLE)
D) RD Pod

Cadence is pretty accurate in all of those. However, if you hold your wrist up for extended periods of time (such as while holding a camera), it can and will impact wrist measurement. It doesn’t have much of a tangible effect for anything else.

Pace can come from the following sources:

A) GPS
B) Wrist based accellerometer pace
C) Footpod (ANT+ or BLE)

Pace cannot come from:

A) HRM-TRI or HRM-RUN or HRM-Anything
B) RD Pod

My general rule of thumb is that wrist based cadence is perfectly fine for virtually everything. Wrist-based pace is usually fine in tunnels and such at your normal running paces. I find that if doing interval worksouts on a treadmill and at the extremes of your running paces (high or low), that you’ll see some deviation on wrist-based pace indoors w/o GPS.

Make sure you are in the right profile and that you have not accidentally enabled GPS that will do what you described.

Are you running Firmware Beta 8.54? If so, there is a related problem where speed and distance are not being captured on bike activities (ie: indoor bike - GSC-10 sensor, reads current speed but no accumulated distance .... had to revert back to firmware 8.00) Wonder if there is a problem with distance accrual for ANY external ANT+ sensor?
