Fenix 5 and foot pod

Does anyone have any thoughts as to why the foot pod so negatively affects your Vo2Max calculations though, I was wearing my foot pod since I got the Fenix 5 for all my runs and my Vo2Max was showing unusually low and keeps dropping even further, now I decided to stop running with the foot pod to see the effect and my Vo2Max is slowly creeping back up to the Fenix 3 levels i've previously seen for the last couple years. I am normally always wearing a HRM-Tri strap for all my activities so even without the foot pod cadence should be pretty solid still.

Is this a foot pod calibration issue or is the GPS pace artificially screwing the calculation giving false higher numbers, basically which one to believe the foot pod paired Vo2Max calculations or without. What are other people seeing with this?

I'm seeing the same thing. I have Run with the foot pod since I got the F5 and my Vo2Max have dropped from 52 to 48 in 2 months. Today I ran without the foot pod and my Vo2Max went up to 50...

I believe footpod have big impact for vo2max


If you will see fenix show me I should run 10km in

47 minutes

But I run faster

And after using footpod my vo2max drop from 56 to 46

Imho, the right V02Max value is the one obtained with the footpod.

I am 50, i've been sedentary for a lot of time, i began to run twice, three time a week since a couple of months. First week of april i bought a 5s, therefore my watch began to store statistical data about my fitness status, training load, Lactate threshold and so on. i wear a garmin hrm chest strap and a footpod, so i let the watch to calibrate the footpod for many outdoor run, using all the metrics coming from the watch (speed,distance,cadence): in this way i obtained a Vo2Max of 40 (wow) and a fitness age of 42. My ego was satisfied ;) but in my conscience i knew that those values were too optimistic. One week ago i set the watch to acquire speed and cadence from footpod and tadaaa: my speed now is more realistic and my Vo2max dropped to 37 (fair). My fitness Age now is 50. For my instance i am more confident with physiological metrics obtained by footpod because imho it is more realistic than the speed obtained by GPS.

My two cents

I'm interested in a foot pod just mainly for distance calculation, and not having to constantly calibrate it as I do a lot of trail runs and pavement runs...

Seems stryd may be the best, but is expensive, will / is milestone foot pod suitable for my needs ?

My experience so far is that even a dynastream pod (I have the adidas speedcell) works fine for pace when used with auto-calibration as long as GPS can provide accurate distance (so far my F5 hasn't failed at this). How ever the calibration seems to change a bit more than with my Stryd depending on speed and type of workout.

According to Fellrnr the milestone is a little worse than the adidas speedcell regarding accuracy.

With Stryd I'd be much more confident to switch distance to foot pod and go for a run where GPS reception was bad as I know it can work very well with just one calibration value. In fact before getting the F5 I did just that. And it seems some people can even use it with no calibration at all.

The only problem with Stryd is that for shorter track distances it still has a bit of lag and for power even a bit more than pace. So in that regard it may be no better than traditional foot pod for distance measurement. From my own testing it seems flying laps seem to give the best result.

Thanks for that, what would you class as a short distance?

Cheers

by reading this post I got convinced that the way to measure speed/pace in outdoors is with the foot pod

what if I configure my F5 to get speed from foot pod always but someday when going outdoors I forgot the foot pod in other shoes?

Willi the F5 take the speed from GPS without changing the settings?

I am the kind of guy that always forget my HRM strap when I want to use it.

Thanks for your answers.

Yes, if the foot pod is absent (not paired) for whatever reason, then the Fenix 5 will default back to GPS for Speed/ Pace and/or Distance.

My experience with the Stryd versus the Garmin (dynastream) footpod is that Stryd is much, much more consistent across a range of paces than the Garmin pod. I used a Garmin pod for a while and got fed up of switching calibrations for different runs, unsuitability for intervals, and so on. Other people found the Garmin pod better than I did, but I think the point that the Stryd is more consistent holds even for them.

My problem with the Stryd, actually, is that the calibration changes every time I switch shoe and is often 5% away from the neutral calibration. (I switch shoes all the time because I keep one pair at work and one at home).
