footpod auto calibration

With the fenix 3 I was never able to get automatic calibration of footpods to work. Consensus seemed to be that it worked, but only under a very specific set of conditions. Is there any information yet about how footpod auto calibration will work with the F5 watches? My guess is it is too early to tell, but I’m putting this out there incase an early adopter has an opportunity to test it.
  • Could you tell me if you use footpod vo2max is lower than when you don't use foot pod ?

    I observe this issue on my fenix 3hr from long time . When I run with footpod i have 48-52vo2max without footpod 54-56
    This happen after 20 running trennings it is takes 2 weeks


    The VO2max I think is more related to hear rate than to pace. Although if you use the footpod to measure the distance, if this is incorrect may occur.
    My vo2max was 62-60 in the last year but yesterday it has dropped to 58, I think by the bad measure of the hear rate. I used a pedometer only for the pace but it was accurate.
  • Having just rediscovered my footpod (literally - I had lost it in the house somewhere), I'm pleased to say that the auto calibration has worked perfectly with the F5 straight away. The instantaneous pace from it is much more usable than the GPS pace especially in urban situations and woodland where clear sky is problematical.

    The footpod auto cal never worked with the F3 and I had to use the Fellrnr tool to set it and tweak it over a number of runs, even then it mucked up my VO2Max estimation so I stopped using it.
  • Did a first run with FP Viiiiva and F5 and the auto calibration worked very well.

    Hi, hoping someone might have some advice. I recently got a footpod for my 5X, primarily because I do a lot of running on fairly dense single track where most wearable GPS devices have come up 20 or 30% short on distance for me. I've done a couple of open road runs with the device set to autocalibrate=on, but the calibration factor stays continually on 100. The first open run seemed "on" distance/pace wise, but the first wooded run (not single track, but fire roads) came up about 20% OVER the known distance. In my situation am I better off going to the track to run 800 meters and then set up a new cal factor based on those results? I assume that then I would leave auto calibrate off after that and just stick with my known cal factor. It's just a bit odd to me that the cal factor hasn't moved from 100. Lastly, not sure if it is related or not BUT with the footpod set to track speed and distance, I see to lose the first 30 seconds +/- and the last 30 seconds +/- seconds from my run after synching with Connect and/or uploading to Strava. After 3 runs, it does that same ~ trimming of both the time and the GPS points associated with the start and finish. Any ideas there? Thanks.

    Could be a coincidence that actually 100 is right for you, a long shot I know, but possible. Using a track to get several laps worth of data and calculating your own adjustment factor would guide you also as whether 100 is spot on or very wrong for you. I’d probably also check that auto pause, auto climb and 3D are set to off during your auto calibrate runs. Might also be worth setting an adjustment factor that is wildly wrong say 85 or 115 and seeing if that is changed after turning on auto calibrate.

    This a crude comparaison but maybe helpful.....I’m 5’ 8” with a stride length of 1.04 to 1.09m and usually a cadence of 185-188 and my calibration factor swings between 95.9 and 96.4

    Good luck

    You also might want to check on the recording type, have it set to 1second not smart, at least for when autocalibrating the footpod......just in case that has an interference opportunity
