Lthr

At the moment , the Fenix 5 only calculates the LTHR and Vo2 max when on actual runs/rides.
However it does not use the data from indoor run and rides even when equipped with footpad(runs) and power/cadence/speed meters (smart turbo trainers)
I live in a very hot country and outdoors activities are impossible during summer especially when talking about lthr runs...thanks

I also do a lot of my training indoors, and agree that it would be useful for indoor runs and rides to be used to calculate training and physiological metrics. Just today, my "training status" score changed to "no status," apparently because all my training runs during the past week have been indoors. Perhaps Garmin doesn't use indoor activities out of concern for accuracy of pace/distance data, but it seems that an auto-calibrated foot pod should be accurate enough.

Does the watch detect your LTHR for cycling? It's found my running LTHR and T-Pace, and it's discovered a new FTP for me three times, but never an LTHR while cycling (outdoors). Is there a setting I need to turn on or something?

LTHR is calculated for running only, FTP is the 'equivalent' metric for cycling. I've had no trouble getting VO2 Max and FTP on indoor bike trainers at my gym (Wattbikes in that case), but there must be a power data transmitted to the watch. Interestingly, I found not having speed and cadence data does not stop VO2 Max or FTP being calculated; it's power data that's key.

U r right just ftp cycling vo2 max on road biking...still shame none of those data can be achieved indoors which is a much more controlled environment

Thanks... i hv a smart trainer with cadence and speed sensors, no such data derived on the watch who van detect all those sensors ... just says improves lthr...no mention of an ftp either...

For cycling, no power data equals no VO2 Max or FTP (it is quite clear on this in the user manual), but if your indoor bike does transmit power over ANT then you should be able to get these metrics. You do need to have HR from a chest strap too - the wrist HR does not provide the HRV to derive these metrics in cycling. Another thing to note, the FTP guided test is VERY hard work; it takes you up in power bands for several minutes at a time, until you explode nearly! (Well that's how it seemed to me at the time)

FYI, your FTP is more like your T-Pace than your LTHR for running. The equivalent metric for cycling would be your cycling LTHR. :)

But thanks for confirming that the watch can only detect your LTHR while running, I thought that was the case.

And I'll agree, speed and cadence are irrelevant (to VO2max and FTP) for cycling. You might be going fast because you're going down a hill, or you might be going fast because of your effort, or, worse, some nebulous combination. And you can produce 200 watts at any cadence you like, by varying the torque you put into the pedal. Power is the gold standard of cycling data.
